SD is not defined. We treat a broken flash drive - programs for restoring a memory card. Operating system errors

Quite often, owners of Android devices face an unpleasant problem when a MicroSD phone. What to do in this case, what troubleshooting methods to apply? First you need to determine the root cause and analyze possible situations.

Why does the phone not see the MicroSD flash drive?

Needless to say, there can be any number of reasons for such failures. Here are software failures of the system itself, and the banal lack of contact between the memory card and the card reader, and violations in the file system of the USB drive, and even physical damage.

However, the situation may look twofold. On the one hand, this may relate to the newly purchased new card, and on the other hand, the problem may lie in the fact that over time the phone has stopped seeing the MicroSD flash drive. What to do in this case will now be considered.

By the way, the issue of compatibility between the card and the phone itself will not be discussed here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards. Moreover, it may be that the card's memory is larger than that stated in the device's support. So in this case, the map will not be determined.

The phone does not see the MicroSD flash drive: what to do first?

If there are problems with an already installed memory card, no matter how it sounds, the cause may be the usual contamination of the device, say, dust. Agree, not every user constantly cleans his phone.

Here the way out is the simplest: pull the card out of the phone, wipe the contacts on the flash drive itself and on the card reader, and then insert it again. By the way, this option is also suitable for new cards. Well, you never know, the contacts just didn't work. Therefore, do not rush to run to the service center or throw away the card you just bought.

Using Recovery Mode

If the simple manipulation of contacts does not help, you can use the special recovery mode (Recovery) provided in any Android device, although you can start with a normal reboot.

To access the mode we need, we use the simultaneous holding of the power and volume down buttons. This is the most common option. But, in principle, each manufacturer can prescribe another combination himself. That's not the point. After starting the device, a special service menu will appear, where you need to select the Wipe cache partition item, after which you just need to reboot the device. If after that the phone does not see the MicroSD, we proceed to more effective measures. They will be radically different from the previous steps.

Problems with the MicroSD card on the computer: what can I do?

Well, firstly, it is worth noting the generally exceptional situation when both the computer and the phone do not see the MicroSD flash drive. It's already worse. On the phone, this problem is almost never fixed.

First you need to insert the card into another device or computer and make sure it works. If it is found, the problem is only with the phone or drive names on the computer. If the card is not detected, the problem is either with the file system or with the memory card itself.

So, for starters, you should use which in Windows is called quickly enough. You can use the combination Win + X and then select Disk Management, or enter the command diskmgmt.msc in the Run menu bar.

This method is good because absolutely all connected disk devices, even unformatted ones, will be displayed in the main window. It is very possible that the letter of the removable card, such as "F", is the same as the designation of the optical drive. We right-click on the map and select the command to change the letter.

However, after such an operation, a situation may also appear when the phone does not see the MicroSD flash drive. What to do, because it is already recognized on the computer? The easiest way to correct the situation would be to partially or completely format the media. However, full formatting with deleting all data and re-creating the file system still looks preferable.

It can be produced either here, or from the standard "Explorer". In both cases, right-clicking calls where and selects the format string. In a new window, you need to uncheck the quick format, and then specify the creation. But, in principle, FAT32 is installed by the system by default. Now it remains to confirm the start of the process and wait for its completion. After that, you can safely insert the card into the phone.

Restoring the MicroSD Card

Now a few words about one more situation when the phone does not see the MicroSD flash drive. What to do if it is found on a computer, but not on a mobile gadget?

First, you should again connect the card to a computer and laptop and carry out a standard check of the device for errors. We use the same "Explorer" with the subsequent transition to the properties menu. There we select the service section and with the obligatory indication of automatic error correction. Also, although not necessary, you can use a surface test with automatic recovery of bad sectors.

Another option involves fixing access to the memory card on computer terminals, as well as normalizing the parameters and system registry keys in the HKLM branch. You should find the SYSTEM folder in the directory tree, in which the StorageDevicePolicies directory is located. On the right side, the defining parameter must be assigned a zero value (usually 0x00000000(0)). After that, the problem should disappear.

Finally, if the card has minor physical damage, which is usually associated with microcontroller malfunctions, you will have to look for special formatting utilities, after knowing the VID and PID parameters. This can also be done using special programs such as USBIDCheck, or by disassembling the card (where the data is indicated on the internal chip).

Then a program is downloaded from the Internet for each card of a certain manufacturer in accordance with known parameters, after which formatting is performed.

Conclusion

If for some reason the removable device is not detected, you should not panic. First you need to determine the root cause of the failures. As practice shows, any of the proposed methods helps to solve the problem. If we talk specifically about phones, here, rather, cleaning the device from dirt, formatting the card or restoring performance, as described in the last version, is more suitable.

By the way, the issue of compatibility between the card and the phone itself was not considered here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards.

What to do if the phone does not see the memory card? Since I often get asked this and similar questions, I answered them all at once in this article. It will be useful for owners of cameras, Samsung, Lenovo phones, laptops - in general, all those devices that support a memory card and refuse to read data on the card.

First, some technical details describing the problem. Let's say, as a result of some manipulations, a mobile device (phone, tablet, smartphone) has ceased to identify a memory card (sd card) even through a card reader. All data is written to the internal memory of the phone, bypassing the actual memory card. This is inconvenient as the sd card is not being used while the mobile device's memory is rapidly filling up. Productivity decreases accordingly.

So, the problem is described in detail, let's move on to diagnosing a phone, smartphone, tablet. Consider the most common reasons why phones do not see a memory card (flash drive) and how to fix this defect on your own using a card reader.

The phone does not see the sd card due to an incorrect file system format or a corrupted file table

Cause of the problem. 1) The file table on the sd card was damaged, the markup fell off. 2) You formatted the memory card yourself, as a result of which the phone stopped seeing the flash drive. 3) The file system of the sd card is unknown (used in another operating system)

How to fix. 1. Find out the size of your flash drive. If the microSD capacity is more than 32 Gb, most likely it is formatted in exFAT. Not all versions of Android support this file system. If you are not using Mac OS, format your memory card to NTFS or FAT.

How to do it, I show in the video:

2. A quick way to fix the problem is to reboot the phone in recovery mode and select the Wipe cache partition option in the Android service menu. This command will clean the contents of the sd card and format the media in the FAT32 file system - it is best suited for storing files on the phone.

Note. We would not advise inexperienced users to perform this procedure: if you mistakenly format the wrong partition, you will lose all data on the phone, including files in the internal memory.

3. A safer (and more convenient) method to format an SD card is through a computer. You will need a card reader and SD Formatter software. It will help you format your flash drive properly.

4. You can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).

The memory card of the phone (tablet) is out of order

Cause of the problem. As a result of mechanical / thermal damage incompatible with life, the phone stopped seeing the memory card or the sd card stopped working. As an option, the phone stopped detecting the flash drive, on other devices the card is also unreadable.

What to do. Alas, nothing can be done with a damaged sd card. All you have to do is purchase a new SD card that is compatible in size and specifications with your smartphone or tablet. The most unpleasant moment is that all the data that was stored on the memory card of an Android or iOS phone disappears completely. You can no longer restore them - neither by connecting a phone with a USB flash drive, nor through a card reader.

If the flash drive still has a warranty and it looks like new (no visible damage), try returning it to the store. If you're lucky, you'll get a brand new replacement card.

Check for bad blocks (bad sectors) via HDDScan

The HDDScan utility (ignore the name) allows you to check memory cards, flash drives for bad sectors and read errors.

To diagnose the problem, it is enough to run the sd card through two types of tests - Read and Write tests. After spending 5 minutes of your time, you will get a conclusion: are there any bad sectors that prevent correct operation, which is why the phone does not read the USB flash drive.

• If the flash drive was purchased recently, we change it under warranty (local or global).
• If there is no guarantee or it has ended, we overwrite the bad sectors with zeros. This can be done through the DMDE program. This procedure will allow you to shift non-working sectors, as a result of which the flash drive will be correctly detected both on the computer and on devices where it was actively used.

Formatting with modern digital cameras

A number of Canon and Nikon camera models, according to user reviews, give a positive result - they format at a low level.

How to fix Sd card through camera:

1. Insert the sd card into the device,
2. In the camera menu, find the format command,
3. Try writing files to a formatted card.

Contact technical support (for Transcend flash drives, etc.)

Their technical support specialists can advise free of charge methods for recovering problematic flash drives. In fact, who, no matter how they are, is best versed in the sd card device? In addition, technical support may offer you proprietary programs designed for low-level formatting (sometimes they are difficult to find on the manufacturer's website).

Give the memory card to specialists for recovery

This option is suitable if you are ready to pay for the work of specialists. This procedure is expensive, but the plus is obvious: you can extract data from a faulty device (though, if the memory chips were not damaged).

The memory card is incompatible with the mobile device

Cause. 1) The mobile device does not support new memory cards. 2) The memory card is too large or uses an unknown technical specification. Therefore, the phone refuses to read the data and does not recognize the flash drive as a storage device.

What to do. Carefully study the documentation for the phone and buy an SD card that will not contradict the system requirements.

Wrong data transfer mode in Android

Symptom. You connect a phone with a flash drive via a usb cable, selecting the Mass Storage option, as a result, it does not appear on the computer.

How to fix. Instead of "Mass Storage", select the "MEDIA TRANSFER" option when connecting your phone to a PC. Explorer should display the contents of the memory card.

The contact of the usb flash drive has come off or the tracks in the socket have been erased

Symptom. As a result of misalignment or incorrect connection, the memory card is not connected to the mobile device, and, consequently, the phone does not see its contents.

How to fix. Remove the sd card from the phone, insert it back in such a way that the contacts of the sd card are correctly connected to the socket.

If the contacts of the sd flash drive are completely worn out, you can buy them for a couple of dollars and replace them yourself (of course, if you have the appropriate skills / minimal experience in repairing and replacing spare parts).

It is possible that the contacts (that is, the tracks on the board) on the phone have been erased, and for natural reasons, he does not see the flash drive at all. A common reason is the natural wear and tear of the phone. In this case, we recommend that you return the device for repair or replace the mobile device.

Software error, as a result of which the phone stopped seeing the memory card

Description of the problem. A certain Android program refuses to recognize the memory card. Other applications read the sd memory card and write data to the flash drive as if nothing had happened.

Solution to the problem. Android does not see the memory card, because in the application settings, the internal memory of the smartphone / tablet is specified as the save source. Go to the settings of the application with which there are problems (for example, Android Gallery or Camera) and specify the sd card as a successor - that is, the place where the files should be saved.

Instructions on how to check the sd card for errors (video):

Answers to questions from readers

After updating the phoneHTC desire 620 g dual sim) microsd is not detected, the flash card is constantly lost. It happens like this: for example, I listen to music, and then it stops playing and the phone writes: "the file could not be opened." In this case, the names of the tracks can be read. What could be the reason?

Answer . Check the audio file format. The player may not be able to read the files of the selected format. So the problem is not necessarily the problem of reading the memory card. If the file format is correct, check the memory card for errors, format it.

I inserted an sd drive into my phone (Samsung galaxy j3 2016), transferred all photos and videos to a USB flash drive, and all photos and videos in the phone gallery were deleted. The files are on sd, but all new photos are saved to the device's memory. I need it to be saved to a memory card and displayed in the gallery.

Answer. If the phone does not see the sd card, try changing the path to the successor in the application settings. It would also not hurt to check if your phone and Android system recognizes the actual memory card. Just in case, turn off your mobile device, remove the sd card and put it back. Turn on the device and check if the files are saved to the USB flash drive of the Samsung phone.

1. The phone does not see the SD memory card (flash drive). SMS came, I opened it - and suddenly I stopped seeing it. Rebooted - still does not see. The laptop sees, the other phone sees. And most importantly, the phone sees another memory card. The brand of the smartphone is Lenovo 650. Please help! Thank you in advance!!

2. Does not read the memory card. I have Windows Phone Dual Sim 535. For a while I had a memory card read, but later the phone stopped seeing it. If you rearrange it to other devices, it is read, but not in mine, but if you insert other memory cards into my phone, then everything is in order. Why does my phone not see the memory card on my mobile device?

3. I cleaned the phone's memory (fly), after that it stopped reading the sd card. The computer reads, but the sd card is not detected on the phone. And he does not see a single flash drive, I tried another card. (Probably, I deleted something superfluous). Tell me how to fix the situation and why the phone does not read the memory card.

4. Prestigio telephone. The phone stopped seeing the memory card. I just sat playing on the phone. Then I put it on for about 15-20 minutes. And when he took it, the notification "" came. I went into the settings - memory, where the external drive is. And there, instead of lines, how much memory is in total, what is the memory card on the phone, there were only two lines.

1. Connect SD card
2. Clear SD card

I tried to press the first one and when I pressed it, the notification "Connecting an SD card" appeared for a second on top (where the notifications are). And below this heading: "Checking for errors." And then a second later, instead of it appeared: "You can safely remove the SD card." Tried rebooting, turning it off and on, pulling out and inserting the SD card. Same on the other device. Why can't he see the flash drive?

5. Mobile devices do not see (do not read) the memory card. The memory card is new, recently purchased. At first there were no problems, but later the phone (Philips s308) periodically did not read the map. The laptop saw it without problems. Soon the phone did not read the card at all, and other devices followed it. The card does not contradict the system requirements. What could be the reason?What to do with it?

6. I have a tabletDIGMA Optimastopped seeing the flash drive after I cleared it in the settingssdcard, restart, turned on, took out and inserted the flash drive back, nothing helped, inserted it into another phone, it seems to have noticed, but does not perceive it. What should I do?

Answer. In the event that the phone has stopped detecting a memory card, you need to check this sd card on a computer via a card reader (the device is connected to a PC via a USB cable and is inexpensive). In your case, the laptop has a built-in card reader. In order for a phone or tablet to be able to read a card or usb flash drive, you need to properly format it using WIndows tools or using special. software. We strongly advise you to use the free SD Formatter program to format flash drives, this is a method we have tested and often works. We hope that after formatting your phone will see the flash memory and be able to write files to it as before. If the card reader still does not see the memory card, all that remains is to buy a new sd card.

I have a smartphoneSamsung Galaxy Gio S-5660. About six months ago I repaired the charging socket and since then until yesterday I did not turn it on. It had a SIM card and a memory card. When I turned it on, it turned out that the smartphone does not see the memory card. Before that, she had no problems. On the memory card and contacts, books, a bunch of photos. Why does the tablet not see the flash drive and how can I revive it?

I wore the device for repair, I thought that the memory card slot was not working. It turned out that it works: it immediately sees a new card.

Answer . On thesdcard, the legs or contacts may be damaged (pins). If you do not notice any damage upon inspection, check the memory card for reading errors. In no case do not format it, otherwise you will not be able to recover files.

Cleared on the iPhone on Android "Phone memory-memory card" after that the sd card turned off. Below it says "Connect sd card" I click - but not what effect. Now there is no memory (the phone was dismantled, but there is no slot for a flash drive). In general, the mobile phone does not see the memory card. Tell me how to return the sd card back to a working state?

Answer. If you don't see a working memory card on your device, it's likely that the file table contains errors. Try formatting the card using the sdformatter application. Since you are dealing with Android, the sd memory card must be formatted in Ext or Fat32.

With the help of the said application, I restored the photo on the Samsung SM-G 318H / DS. They remain in this application, I can’t transfer them to the gallery or to the SD card, how can I do this? Why does not see the memory card?

Answer. Your question is formulated very ornately, so it's hard to say why the phone does not detect a memory card. It looks like the problem is not with your phone's flash drive, but something else. You need to copy the files to the DCIM folder on the device, then they will be displayed in the Gallery again.

I moved the SIM card from the tablet back to the smartphone and all the memory from the phone disappeared. What to do and is it possible to restore photos and contacts if the smartphone does not see the flash drive.

Answer. In your case, probably not everything is so sad. You may have moved the sd card (flash drive), as a result of which it moved away from the smartphone socket. Check the connection between the socket and the phone's memory card. If contacts are lost on the flash drive of your smartphone, try importing contacts from the SIM card through the standard Android address book or synchronize contacts with your Google account.

Samsung Galaxy A5 2016 phone. I inserted a 2 GB Qumo sd card (new card, just bought) into the second slot (for the second SIM card and sd card). The phone does not see it, either simply through the phone's menu, or through a cable connection to a PC. What could be the reason, somehow you can "reanimate" the memory card?

Answer. Qumo memory cards don't have a very good reputation. However, 2GB cards usually don't have problems when connected to a phone.

First, connect your memory card to your computer via a card reader. If the computer does not see the memory card (the disk is not displayed in Explorer), give the card (explaining that the computer does not see the sd card) to the seller and return the money.

If the sd card is not readable only on the phone, and everything is OK on the computer, try formatting the memory card by selecting FAT as the file system.

The Samsung Galaxy S5 smartphone stopped seeing USB flash drives (I saw and read it before), the smartphone is practically new. Other devices, flash drives are detected without problems. Why Android does not see the flash drive, how to fix the error?

Answer. There can be at least two reasons why the phone does not see the flash drive. Try to fix it like this:

1. Check if debugging is enabled on your phone (try enabling/disabling).
2. It is advisable to format the flash drive in exFAT, otherwise Android may not read its contents.

I dropped my phone and all the photos in the gallery in the camera folder disappeared from the memory card. Can they be restored somehow? The rest of the folders remained in their places.

Answer. Perhaps the sd card is damaged or Android does not see the sd card. Check if the sd card works if you connect it via a card reader to a PC. Another reason why the phone does not see the SD card is that the card has physically shifted in the slot when dropped, so at the same time check the connection of the contacts.

As for the direct answer to the question: if the memory card is intact, you can restore the photo with any application, starting with CardRecovery and Recuva.

The problem is doubly unpleasant, because the phone was bought a month ago. I decided to transfer some audio-video files from my old phone. The new smartphone is j7, and the old one is also Samsung Galaxy Grand Neo… The data transfer went smoothly.

About a week later I looked at sd, and the map did not appear from my native "my files". I looked through the RAR program, through the xplore file explorer. There all the folders were displayed, but were empty. But it's important to add this: there were music and some video in the phone's memory. So, they were displayed, but they were not "empty", but refused to be reproduced - "playback error". On an old phone with any sd and different ages, this has never happened, so what it was, but not this. And this recorded map can be read normally on the old phone, no problem.

For me, the main thing, as you understand, is the phone, is it the reason? Such refusals in reading for a month were twice with the internal memory, and four times with the seat. Reboot - and everything is fine. But this is not the norm for the phone?

Answer. There may be several reasons for this behavior.

Perhaps the cause of the error lies in your way of copying files from internal memory to external. Try different ways and test: for example, through a card reader on a PC, through a file manager on a phone, etc. Do you see the described reading error in all cases?

However, since you noted that there are no problems with other flash drives, then there may be a problem with the memory card. Who is the manufacturer, is the sd card compatible with your phone model? Read user reviews.

Third - update the software on the phone and remove unnecessary applications.

Fourth - format the sd card with the SD Formatter utility. Try different file system formats.

1. Last chance to find the answer to my problem. The Samsung galaxy not 5 (china) phone uses only its internal memory, and the flash drive is not detected. What I just didn’t do ... And I put a checkmark, and inserted it into another mobile phone, formatted it this way and that - it doesn’t help.

2. On the phoneSamsung Galaxy A3 memory card not workingmicrosd16 GB. For almost half a year she was in the phone, all the photos from the camera were automatically saved on it. The memory card has not been removed since the time it was put into the slot once. I have been using the phone for almost a year. Previously, there was another card, with a volume of 8 GB.

R.SI moved the card to another phone - he does not see it either. And the computer doesn't recognize it either. What to do? On the flash drive are all children's photos and videos taken in six months.

Answer. If the smartphone or tablet does not see the flash drive, the problem may be in the application that does not save files to the right place. Check in the settings where the files are saved - to an sd card, flash drive or to the internal memory of a tablet / smartphone. For example, in the Android Gallery settings, you can change the storage location for photos.

Re-read the article. If all else fails, then perhaps the phone does not see the microsd memory card, because it is out of order.

The phone does not recognize the memory card. Transferred everything to internal memory. When the card is disconnected, all files are read, but not when connected. Now, when you turn off the SD card, the internal memory is also turned off and there is nowhere to save information. Tell me what can be done if the memory card is not readable (if possible).

Answer. Until this time, the memory card worked? Your phone may not support this card model.

If the sd card worked before, you may need to format your card - and it will be writable again.

The question is formulated incorrectly: you write that when the memory card is turned off, the files are read, while you say below that the internal memory is turned off. So where are the files being read from then?

1. The phone worked with a memory card. With a congratulatory video, they sent a virus that could not be removed. Delete it and it reappears. I tried to reset my phone, but it didn't work. It didn't find any updates. After some manipulations in the recovery menu, he became different, found updates, downloaded and installed them. The firmware shows its own, but with a fresher date.

After that, the sd card is not detected. Android does not see it and does not determine its memory. And other sd too. Without a card, the phone sees its memory and works fine. What to do if the phone does not see the sd card after the actions of the virus?

2. I put an sd card in the computer - everything reads well there, you can see. And in the phone there is an inscription: SAFELY REMOVING THE CARD. Why does the phone not see the memory card? What to do?

Answer. If the phone does not see the memory card, this may be due to damage to the file table on it. How this is connected with the recovery, it is not clear. Try formatting the sd card. If nothing changes for the better - change the firmware.

1. I bought a 4G micro flash drive in my phone, installed it in a computer via a card reader, wrote files and installed it in my phone (Microsoft Lumia 530). After a while, I installed it again in the card reader and connected it to the computer. Windows gave a message that the device is faulty and does not read the USB flash drive, but everything works fine through the phone. And this happens with all usb media and devices. I checked flash on many computers before installing it on the phone - everything is OK. After installation, the memory card does not work on the computer - only through the phone.

2. I ordered a flash drive forebay(flash drive universali- flash device). Yesterday I received it, inserted it into the phone - it works, it also works on the computer. Today I tried to transfer a video from my phone to a USB flash drive, copying began, I left the phone and went away. Upon returning, I found that the program was closed, and the flash drive was no longer detected on the phone, nor was its computer detected. What to do?

3. I bought a 32 GB flash drive in my phone from Aliexpress. It worked fine, then the photos that were saved to it were cut off halfway or instead of them there was a gray screen. In the end, it stopped being detected by the phone. The computer seems to detect it, but does not tear it off. Writes something like "insert disk". I tried a lot of things that were written on the Internet, a lot of programs. Some do not see the flash drive, some see it, but still cannot format it.Tell me how to make her feel.

Answer. Format the flash drive via phone or Recovery (we wrote about this at the beginning of the publication. If it doesn’t help, go to Windows Disk Management and check if the flash drive is mounted when connected to a PC, if the volume is displayed in the list. If necessary, you can create a new partition on the flash drive and format in FAT or extFAT using specialized programs.

I turn on the music on the phone, he writes: there are no music files. Phone nokia RM-1035 and mirex micro sd (HC) class 4, everything worked yesterday. Probably, the memory card is not readable! How do you know if it's working or not?

Answer. Check if other mobile applications see the contents of the memory card, for this you can install another player. Connect the microsd card to a computer or laptop through a card reader. If the flash drive is not available in both cases, try the other methods described in the article.

The Samsung Galaxy A3 2015 phone does not read the flash drive. I formatted it in all possible formats, but it did not help. Connected to a PC - everything works fine. Why does the phone not see the flash drive? Maybe something in the settings of the phone needs to be changed?

Answer. Go to Settings - Memory. Check the "SD memory card" section. Install a file manager and see if the files on the memory card are displayed on it.

In addition to standard formatting, you can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).

Another reason why the phone does not see the sd card may be the lack of contact between the memory card and the phone. Check if your device reads other flash drives. If not, take your phone in for repair.

Doogee x5 phone. The phone did not see the memory card, but it was there. Accidentally transferred data to external memory. For some reason, the transfer was made, but the map was still invisible. Pictures, videos, music, safely disappeared somewhere. How to get them back and why the phone does not see the memory card? Is it possible to restore all this somehow? Tried Android Recovery - to no avail.

Answer. If the phone does not see the sd card, then how did you transfer the files to it? Perhaps you just copied them to another place.

Try to connect the memory card through the card reader to the computer and scan it with the CardRecovery program. As for Android Data Recovery, this program is less functional.

After disabling the sd card to work in aparted and performing manipulations in it, the prestigio phone does not turn on the sd card again. By the way, the laptop does not see the memory card either. Actions in recovery did not help. What to do if the phone does not see the memory card?

Answer. Perhaps the operating system and the laptop see the sd card, but the markup has fallen off. You need to create a volume on unallocated space. Start - Run - diskmgmt.msc. Find the unallocated area and use the context menu to create a new volume on the sd card, assign a letter, apply formatting. The sd card disk after these manipulations should be determined as before.

I connected the camera as in the instructions (via the USB port), but the camera reads as a Portable Device, but it needs a Removable Disk. The camera does not see the memory card in connection mode or what is the problem? How can I change the display? Camera Nikon Coolpix S9400.

Answer. Your camera supports SD, SDHC and SDXC memory cards. The computer does not see the memory card as a drive. You need to remove the card from the camera and connect it to the PC via a card reader. If you have a card reader built into your laptop, it will be even easier to connect the card. After that, you will see the removable disk in the list.

mico sd 32G in android tablet. I will twist in the connector - everything is ok, but after a while the conductor does not see it and through the settings menu, the SD card memory does not turn on. if you pulled out and inserted a memory card, it appears. I cleaned the contacts, wiped them with a rectifier, but still Android does not see the sd card where the dog is buried?

Answer. Try testing another sd card with your phone. If the situation repeats itself and the smartphone does not see the flash drive (the memory card disappears from time to time) - most likely, the matter is in the contacts of the phone.

If another memory card works without errors, we advise you to format the problematic card in FAT32 or exFAT - in case the phone does not see the micro SD flash drive due to errors in the file table.

The phone (Samsung Galaxy S5) does not read the memory card. I inserted three cards, and does not read any of them, although they are correctly displayed on other devices. In this case, the inscription "Connect SD-card", the font of which was previously gray, becomes white and available for pressing, but if you press it, nothing happens. All photos and pictures in the gallery (located in the phone's memory) are not displayed. And applications that are not in the internal memory, but in the phone's memory, do not open. Tell me what to do?

Answer. There may be a failure at the level of the Android operating system or installed applications. Try to manually resolve the conflict by deleting any unnecessary apps from your phone. Update the OS version to the latest through Android settings.

If the phone still does not see the memory card, check the phone contacts: are there any visually noticeable damage on them?

Do you write "on other devices" while referring to the computer? If yes, it is likely that the file system of the flash drive is NTFS, but you need to format it in FAT or exFat.

When I insert an sd card into the phone, the device does not detect it. Whatever I tried: even inserted into other phones, still does not see and does not read its contents.

Answer. There is too little information about the memory card (it is practically non-existent) to give specific advice. First, check if your phone supports sd cards of the size that is on your card (see the documentation for your smartphone or tablet). If you have just bought a memory card, you can exchange it under warranty for another one - a smaller one.

If you have previously used this memory card and it is no longer detected on this and other mobile devices, it is most likely out of order.

1. I cleaned the sit card on the computer. Deleted everything from her. Now the new smartphone teXet X-plus TM-5577. I inserted a sit card, he sees it, but nothing is downloading on the sit card and I can’t transfer anything to it. Tell me what to do?

2. The phone started to turn on by itself periodically (Lenovo A 526). Then I went out of the house and plugged in the headphones and noticed that not a single track was playing. Later, when I took out the phone, I found that the flash drive was not readable and the saved music was not playing. I tried to reboot the phone - it does not help, I put it in the card reader - it sees a memory card, I put it in my friend's phone - too. And I don't want to. And the most important thing that knocks me out of my thoughts is a notification after turning on the phone with the phrase "Dismantle the MicroSD before deleting so as not to lose data.

Answer. You need to reconnect the memory card to the computer (as you did before), format the sd card in the standard way (for example, through Explorer) or using sdformatter. The file system is FAT32. Most likely, it is due to incorrect formatting that the phone cannot write data to the memory card.

After a sudden shutdown, the tablet (android 5.1) stopped recognizing the memory cards in the card reader normally. Writes either error checking is in progress, or reading is in progress, which lasts indefinitely. At the same time, half of the programs stop responding, everything slows down wildly, and it becomes impossible to turn off the tablet (only when it is discharged to 0 and cut down). Sometimes (very rarely) after connecting, he sees it, but at the slightest manipulation with the card (even viewing a photo), he immediately loses it and starts re-reading it again, and already with the ends. Tested on 3 flash drives, both clean and not, with different formatting and a bunch of dances with tambourines (all according to recommendations on the forums). The system was reset. Nothing helped. He refuses to see a card for 8 gigs at all, although if you connect it through an adapter to a usb connector, everything works fine (like other flash drives). What is the problem, in the card reader or in the system?

Answer. It is best to connect the problematic memory card to a laptop or, alternatively, through a usb adapter, as you mentioned. Next, the sd card needs to be formatted.

Most likely it's the card reader. Many cheap card readers stop reading memory cards correctly after a short time and give copy errors or read information slowly.

The system (Android) is unlikely to be related to the problem, since you have already tested several memory cards. Perhaps it's a specific application that slows down the system, but this can only be calculated by resetting the phone to factory settings.

Phone Lenovo vibe shot, android 6. costs sony sd card 32gb in the option as an extension of the main memory (ext4). The phone stopped seeing the file system - writes SdCard0 01/01/1970, 00 kb. Windows 7 sees two sections - 16Mb and 30Gb, serviceable, free 100% each.

How can I return everything to its place with the restoration of the old files? well, or at least how to pull out photos and a folder of vatsap?

Answer. R.saver or AOMEI Partition Assistant Standard Edition are suitable for recovering a deleted partition on an sd card. If the file table on the partition contains errors, you can try to fix them using the chkdsk utility under Windows. If it doesn't help, try scanning the sd card (unreadable partitions) with the Recuva utility. Until you overwrite the information on the flash drive or format it, the chances of getting the files back remain high.

Samsung A3 2017 Samsung memory card 64 gb. Created folders from the computer: photos, ringnotes, music, videos, movies, etc. The phone sees only audio, pictures, documents, videos. Other folders do not see on the memory card. What needs to be done?

Answer. Install any file manager for your phone (for example, Total Commander or ES Explorer). Create folders directly through these programs and copy everything you need there. The files should be readable on the memory card without problems. It is also possible that those folders that are not readable from the sd card are hidden or corrupted. So it will not be superfluous to format the card in order to avoid further errors.

Lenovo A2010 phone does not see sd memory card. tried to reboot, writes "Only one sd card is available, it is impossible to perform switching." Other phones do not have a card. In the computer through the card reader does not show at all. Is this really the end, so many photos and videos are gone? Maybe something can be done?

Answer. It looks like there are reading errors on the card or the markup has fallen off. Since the memory card does not open on the computer (i.e., the letter / separate drive is not displayed in the file manager), it makes sense to check if the memory card is recognized as a device at all. To do this, go to diskmgmt.msc (Start - Run) and see if unallocated space appears when you connect the sd card to the PC. If it appears, create a new file volume in this space via the context menu. If nothing happens, most likely the sd card is out of order.

Phone model sony xperia m4 aqua dual. Within two years, a microSD memory card was installed in the phone. Recently, failures began to occur: at first, in order for the memory card to work, it was enough to restart the phone. Now the phone does not see the map at all. Formatting failed. Installed a new one. The phone recognizes it (it is in the settings, the photos were sent to the card), but the applications cannot be downloaded from the play store (it still shows the download option only to the phone's memory). What needs to be done in this situation with a flash drive?

Answer. Format the memory card with specialized applications - the same SDFortatter is fine. Next, check the card for errors using the chkdsk tool.

However, you clarified that changing the memory card does not help. The problem may be caused by specific applications or software conflicts within the Android OS. In this case, we advise you to update the firmware or, as an extreme option, reset the phone (perform a hard reset).

Samsung A5 2017 stopped seeing it after encryption of the SD card. Through the card reader on the computer sees, but does not open. Tried to format (SDFormatter, cmd) - does not work. Sees other flash drives. I checked for errors - it gives an error, but does not fix it.

Answer. To check the sd card, use the following options:

chkdsk (drive letter): /f/r

• /f - fix file system read errors
• /r - fix bad sectors on sd card

This should fix the errors and allow you to format the sd card in the standard way or through utilities like SDFormatter.

there is a Kingston DTSE3 16G usb drive, the computer does not see it, the flash drive is not readable. periodically the system gives a message that the device can work faster or the device is not recognized. Are there any recovery programs?

Answer. The flash drive supports the USB 2.0 interface. Your computer (motherboard) may have an older version of the ports, due to which a similar message appears. Therefore, we advise you to update the hardware of your PC if you have not done this for a long time.

Recovery programs will not help you, but the correct formatting of the flash drive (in NTFS / FAT) and subsequent error checking through chkdsk will not interfere.

Answer. If there are important files on the memory card, make a copy of them on your computer. After that, format the memory card and check it for errors. If everything is in order, you can use the sd card on your tablet or phone, write files to it. If the situation repeats, update the tablet firmware or perform a hard reset. However, this is already an extreme measure, we advise you to deal with reading errors first.

Hello. Your the computer does not see the flash drive , memory card or hard drive and you are wondering what to do? Surely every computer user has a similar situation, or even more than one.

Today I will help you with this question. I'll tell you what are the problems with displaying usb devices and how to solve them. By the way, the last article was about data recovery from a flash drive. If you are interested, then replenish the baggage of your knowledge.

Your computer does not see or recognize the flash drive, hard drive and memory card. Let's look at the possible reasons for this situation. At the end of the article, do not forget to watch a visual video tutorial on how to make a flash drive or hard drive work.

A small outline of the article

• Device definition


• Power indicator


• Front USB ports


• Lack of nutrition


• usb disabled in bios


• usb device not recognized


• Outdated drivers


• Viruses


• Different file systems


• Conclusion

We define the device

The first step is to determine exactly how the computer does not see your usb drive. From this answer it will be clear whether it is possible to recover data from a flash drive or not.

To do this, you need to go to the Windows Device Manager.

In order to enter it, you need to right-click on the shortcut of my computer on the desktop or in the start menu, go to properties, click on device manager.

Then select disk devices.

We got into the device manager and the disk devices tab. If your flash drive or memory card is displayed in this list, then with a high probability you can recover data on them. If the flash drive is not there, then most likely the memory card controller has burned out. I recommend trying to connect your usb device to other computers.

If nothing changes and the flash drive is also not visible, then the problem is probably a faulty controller. From such a usb device, you can hardly pull out data, you can, of course, contact special institutions that deal with this (they are not available in all cities), but they will charge you a tidy sum for work. So think about whether you need it or not.

Your flash drive is visible as a device, but it does not appear in my computer or explorer, or it asks to be formatted. To do this, you need to go to disk management. To access it, you need to follow these steps. Here are screenshots for clarity:

The device is displayed, writes its volume and file system - it is ready for use and functions normally.

The device is displayed, shows its volume, but does not display the file system and writes "not defined". In order to use it, you need to right-click in the undefined box and select format. You can check the quick format box and click OK. After the device is formatted, it should work in normal operating mode.

Displayed as a removable device, writes no media and does not show the file system. All these parameters indicate that this device is not working properly, there are internal or external damage to the controller. You can hardly read information from such a flash drive without special expensive equipment.

Power indicator

When the flash drive is connected to the computer, a small indicator on the usb device should light up. If it caught fire and started blinking, then everything is fine with the flash drive, but not with the operating system, you need to look for the reason in it. If the flash drive indicator does not light up, then the problem may be in the device itself or the connected port on the computer.

Front USB ports

There have been cases when a flash drive is connected to a computer through the front usb ports, but the flash drive does not work. Perhaps these front usb are turned off or they forgot to connect them to the motherboard.

Not enough food

The lack of power mainly occurs when connecting hard drives through the front usb ports of the computer, hubs and hubs. It is best to connect such devices directly to the usb connectors on the motherboard, that is, on the back of the computer. If you are using a usb hub or hub, then disconnect unnecessary devices, maybe this will help. Also, the reason may be in the low-powered power supply of the computer.

usb disabled in bios

This problem rarely happens. Mostly in computer clubs and similar entertainment venues. What is it for? So that a person does not bring viruses and does not download various programs and unnecessary information to the computer. It's more of a protection measure. If this is a home computer, then you need to go into the BIOS settings and check the box to enable the launch of usb devices on the motherboard.

usb device not recognized

The usb device is not recognized and when a USB flash drive is connected, the operating system gives it an already used letter (used volume label). This does not always happen, there are other cases. In order to fix this, you need to go to the computer control panel.

I showed how to enter it above, or you can call the Run window - the keyboard shortcut Win + R (the checkbox between Ctrl and Alt plus the letter R) and type the command diskmgmt.msc. Go to disk management, find the desired device - a USB flash drive, right-click on it and select Change drive letter or drive path. In the window that appears, you can add or change this letter.

Outdated drivers

It is possible that you have outdated drivers - update them. To do this, you need to find out which company is the manufacturer and model of your motherboard. Usually written on the box with the packaging, if you saved them of course. If not, then use the Everest or Aida program. With the help of them, you can find out the model of your motherboard and a lot of other useful information about your computer. After everyone knows, you need to go to the official website of the manufacturer, find the required motherboard and download the drivers for the chipset and usb device, if any.

Viruses

There have been cases that the computer does not recognize the flash drive due to viruses that have appeared in your operating system. To do this, I recommend using good antivirus programs and doing a full virus scan at least once a month. If you don't have it, you can use the free antivirus Kaspersky Yandex version, or purchase a paid product.

Different file systems

This happens, but very rarely. Your computer does not see the flash drive due to a conflict between the file systems of the computer and the flash drive. Most flash drives work in two file systems FAT and FAT32, and hard drives in NTFS.

You can try formatting your flash drive in another format such as FAT32 or NTFS. Maybe everything will work fine after that.

Useful information. On a flash drive in FAT and FAT32 format, you can upload information in one file no more than 4 Gigabytes, and much more on a hard drive. Therefore, if you encounter such a problem, be prepared for this and keep in mind.

And for dessert, watch a short video tutorial on how to make the computer see a USB flash drive and hard drive. For convenient and enjoyable viewing, I recommend watching this video in full screen, that is, in full screen mode.

The computer does not see the flash drive and hard drive

Most information today is stored on flash cards. Photos or movies, documents or other information on the microSD card can be easily read through the adapter in the laptop. When there are problems with the reader, the exchange of information becomes impossible, which creates a lot of problems for the user.

To date, of all types of portable memory cards, microSD flash cards are the most convenient and widely used. They are used in phones, smartphones, players, tablets, cameras and other portable and computer equipment.

To figure out why the laptop does not see the micro SD flash drive through the adapter, you can try to find the cause and fix it yourself, or use the help of Orion Service specialists.

Features of reading from a microSD card

To read data from microSD, you need an adapter, which is usually included with the purchased flash card. To turn it on, the USB flash drive is placed in the adapter, and the adapter itself is connected to the connector on the laptop (the SD connector on the side or front of the laptop panel). If the flash drive has a new format, such as SDHC, some obsolete laptop models may not recognize or read this type of flash card. The solution to this problem is to purchase an external card reader, which is enabled via the USB port.

Possible causes of the malfunction and their solutions

A laptop may not see a microSD flash card due to many reasons.

Software error

You can determine the status of the OS and software by testing the laptop with utilities that allow you to see all the errors that have arisen in the work. For accurate diagnosis, it is recommended

return the laptop to the service center "Service Orion".

Missing the right driver

If there is no driver on the laptop you just bought, you can install it from the disk that comes with the product. If the laptop is of an old model, bought from hand or has been formatted disks, it will not be difficult to find the right driver for it. To do this, you can use programs to update drivers.

Laptop virus infection

There are a number of virus software that block the device's ability to freely access disks. The solution to the problem is to run an antivirus program, recognize malware and remove it.

Flash drive failure

To make sure that the microSD flash card is broken, you need to install it in another laptop or device. If the problem reappears, the reason lies in the flash drive itself; if the laptop sees it, you need to look for the reasons in the device itself.

In order to restore the performance of an external storage medium, you can try formatting the disk. The procedure proceeds with the cleaning of all information recorded on the media. Formatting can be requested by the laptop system itself or forced using a command in the context menu (if the flash drive is identified by the laptop and displayed in Explorer).

Card reader does not support microSD card reader

To fix the problem, you can buy an external card reader or order a replacement for the old card reader through a hardware repair.

Drives have the same letters

One of the problems that you can fix yourself is the coincidence of the letters of the hard drive and flash drive (for example, the letter F). In such a situation, "My Computer" reflects only one drive, usually built-in, not external media. To fix this situation, you need to change the drive letter through the Disk Management dialog box (Win and X keyboard shortcut command).

If you need to urgently copy or use information from a microSD card, you can not use a USB flash drive and adapter at all. For example, reading data is possible from a card on the phone without removing it. All you have to do is connect your phone with a USB cable to your laptop. In Windows 7 and 8, there is no need to install special software for this, as the system automatically selects a driver, recognizes a flash drive and reads video, photos, text files and files of other formats.

Sometimes a problem can arise due to a banal loss of contact. This usually happens when you frequently remove and insert a microSD flash drive into the adapter. Trying to remove and reinsert the memory card may resolve the issue.

If all attempts to correct the situation on your own did not give the desired result, you can repair the breakdown at the Devay Service company. Here, specialists conduct a complete diagnosis, determine the exact reason why the laptop does not see the microSD flash drive through the adapter, and quickly restore this function of the laptop at affordable prices with a guarantee for the work done. In this case, the repair time is a matter of hours.

A huge number of users of computers, cameras, phones and other devices around the world use CD-drives. This is one of the most popular ways to store data and will be around for a few more years. This is explained by the fact that the built-in memory of various devices is often not enough or it is completely absent.

But what if the computer for some reason does not see your memory card from the camera? Why is this happening and can I fix the problem myself?

Reasons why the computer does not see the camera memory card

The first step is to establish the reasons why the computer does not see the memory card. First you need to understand where exactly there is a malfunction - in the computer or in the drive itself.

Only by knowing the exact cause, you can choose the right sequence of actions that will correct the situation.

The reasons can be different: from the incompatibility of the card and card reader to physical damage to the drive. Most often, users also have to deal with operating system errors and viruses that have entered the computer. In some cases, you need to update drivers or check file systems for compatibility, as well as make sure that the device as a whole is working.

Reference! In some other cases, it is possible to assign a letter to a flash drive that already exists on some other removable disk. As a result, this leads to the fact that it is not displayed at all on a computer or laptop. In this situation, it is enough just to change the name for the data to appear in the file system.

What to do if the computer does not recognize the camera's memory card

Check if the card works on any other gadget. If there is the same device, then try inserting it into the computer. This way you can easily check the compatibility of the card reader and the card.

If you understand that the problem lies in the drive itself, then you can try installing a special program that, in some cases, can restore the operation of the card. It's called HDD Low Level Format Tool. In order for everything to work out, you need to download the application from the official website of the manufacturer and install it correctly on your computer. There are other similar programs.

Study each of them on the Internet and choose the most suitable one.

An important point is also updating drivers. If your drivers are outdated or not available at all, then you should download them from the website of the manufacturer that manufactures your computers.

To eliminate viruses and prevent their occurrence in the future, you should install a special anti-virus program. The most popular at the moment is the Kaspersky program.

In case of errors in the operation of the operating system, you need to restore the system, for which the "Control Panel" is used.

If you had to deal with the incompatibility of the card reader and the memory card, then you just need to use a special explorer. In the event of a malfunction in the card reader, it is unlikely that you will be able to fix something on your own. It is best to contact the service center for professional help.

Rules for handling memory cards

Not all users know that sometimes memory cards fail due to improper handling. Such errors can lead to irreversible consequences.

For example, you cannot eject the media while it is in use - to do this, you must complete all ongoing operations. In addition, memory cards should not be stored in places with high humidity and should not be carried in a pocket along with keys and other metal objects at all times.

It should be understood that such media in any case may stop working after prolonged use - they tend to wear out, so it becomes necessary to purchase new devices.

Now you know why the computer may not see your memory card from the camera and what can be done in this case. You should not panic and think that all files are lost. In most cases, the problem can be easily and quickly solved by yourself.
