Why the phone does not see the sd memory card or usb flash drive. What to do? Android does not see a flash drive (memory card) microSD Empty sd card android

Good day everyone!

Today, the popularity of SD flash drives, I think, is not inferior to USB flash drives. Judge for yourself: phones, tablets, cameras, cameras - SD flash drives (sometimes called SD cards) are used everywhere!

In general, I must admit that SD cards are quite "capricious" devices, and it is not uncommon that the computer does not recognize or see it. In these cases, usually, we immediately remember that there are important photos, files, data on the flash drive - which simply need to be 100% returned and restored! ☝

In this article, I will give the most common reasons for the invisibility of an SD card by a computer (laptop), as well as recommendations for their elimination. I hope my humble advice will be useful to someone.

Many users confuse one point (although it is not a key one, it will help in solving the problem). I will show it on the example of one user question.

I took the card from my phone (microSD) and inserted it into my new device, but he offered to format it.

Then I brought it back to old phone, but he also wanted to format it. My laptop also does not see this card and offers to format it. What to do? Help to recover data from a flash drive.

Illustrative case. The laptop sees your flash drive, and even offers to format it - i.e. he does not understand that there is data on it, cannot recognize your flash drive, cannot read the file system (in this case the file system is marked as RAW).

This often happens due to:

file system failure on a flash drive;
Windows cannot read an unfamiliar file system (for example, it often happens with disks connected to a TV - it can reformat them into its own file system, and then Windows does not see it).

By the way, many people make one mistake when connecting the microSD to the computer: when inserting the card into the adapter, they do not push it all the way (see photo-1 below). As a result, the PC simply does not see anything when the SD adapter is connected.

Checking a flash drive: fixing file system errors

In this case, you can try to restore the flash drive and all the files on it using the error checking and repair utility - chkdsk (built into Windows).

To do this, do not agree with the Windows suggestion to format the media (screenshot above), but simply 👉 (Easiest way: press Win+R, then type CMD and press Enter, see screenshot below).

Check disk / flash drive

An example of recovery is shown in the screenshot above. After such a simple procedure, the flash drive returned to its working state and functions normally to this day. 👌

When the check succeeds, usually command line reports something like: "Windows has checked the file system and found no problems. No further action is required".

As a rule, if there was a small file system failure, then chkdsk it will be eliminated and the flash drive will become readable (after this procedure, it will be able to read both the phone and the laptop).

Now what if chkdsk did not help, but you need to restore files from a flash drive... 👇

Restoring files from a flash drive

If, after trying to fix errors, Windows still intends to format it (that is, the OS sees it, but does not recognize it), then first of all, I will recommend that you restore files from it (unless, of course, you need them).

After you format the USB flash drive, it will be more difficult to recover data from it (and if you write new files, it will be impossible at all!).

There are special programs for data recovery. Some free and popular ones, I will give in the table below.

3 free programs for data recovery

Recuva

On the official website

R.saver

On the official website

Pandora Recovery

On the official website

Advantages:

recovery wizard: will guide you step by step through all the "thorns" and difficult moments in this procedure;
the ability to recover files even from damaged media;
support for flash drives, SD cards, hard drives, SSD;
file systems support: exFAT, FAT32, NTFS;
the ability to search and restore an unsaved Word document;
preliminary assessment of the possibility of recovering a particular file;
fast and deep Scan disk.

Advantages:

file systems support: exFAT, FAT12, FAT16, FAT32, NTFS, NTFS5;
the ability to recover deleted files;
the ability to reconstruct damaged file systems;
data recovery after formatting;
automatic setting of parameters for recovery (relevant for novice users).

Advantages:

recovery of not only "normal" files, but also hidden, encrypted, compressed, and system files;
simple and intuitive interface;
there is an evaluator: evaluates the possibility of recovering certain files;
the ability to recover files on network and disk drives (including flash drives);
Russian language support;
support Windows 7, 8, 10.

In principle, you can use any of the recovery utilities. More simple for beginners is Recuva, which has a wizard in its arsenal that walks the entire procedure step by step from A to Z.

The screenshot below shows my scanned hard drive in Recuva in order to search for old deleted pictures, photos. Many of the deleted files were found and restored (a green circle in front of the file is a good sign, it means the program appreciates the possibility of recovery).

Important point: when restoring files - restore them to another medium! ☝ I.e. if you want to recover a file from a flash drive, save it to your hard drive (if you save to the same flash drive that was scanned in the program, then the recovered file will overwrite other unrecovered data). Such is the tautology...

In general, the recovery procedure requires another rather voluminous article (to dot all the 👀).

Formatting a flash drive

Option number 1

If you don’t need data on flash drives or you have already restored them, and Windows still continues to ask you to format the media (that is, a microSD card) - just agree ...

Option number 2

You can also format the flash drive by going to "My computer" / "This computer" (screen above) :

First click on SD card right click mice and from the context menu select " Format";
Next, select a file system (I recommend starting from what file system is supported by the device in which it worked / will work. As a rule: FAT 32, exFat);
Click the button "To begin"(Windows will ask you if you really want to format the media - agree...) ;
If everything went in normal mode- you will see a message that formatting is complete (each step is shown in the screenshot below).

Option number 3

If in " " your flash drive is not visible, or Windows cannot format the media - you must use special. utilities for working with such flash drives.

How to format SD card in HDD Low Level Format Tool:

Letter conflict: drive letter change

In general, when you connect a drive (including a flash drive), Windows automatically assigns a letter to this drive (for example, F :).

But there is such a "glitch" that the letter is assigned incorrectly: for example, the one that is already in the system - as a result: a conflict occurs and your flash drive is invisible! 👀

Therefore, in case of invisibility of the flash drive, the first thing I recommend to do is go to " ": look up the drive letter, change it (it is possible to format the media).

1) To do this, first press the buttons Win+R , to a line "Open" enter the command diskmgmt.msc and press Enter.

2) Next, find in the list that disk (microSD card) that is not displayed (not visible) for you. Right click on it (sign-1 on the screen below) and from the context menu select "Change Drive Letter or Drive Path" .

1) If the required flash drive is not in the list in "Disk Management", go to the next subsection of this article.

2) If the file system is marked as RAW, the flash drive must be formatted (more on this at the beginning of this article).

Change drive letter

3) In the next step, press the button "Change"(number-1 on the screen below), then set the slider to "Assign drive letter (A-Z)" and choose some unique letter (the one that is not in the system).

Agree with the changes made. Sometimes, you may need to restart your computer (laptop).

If the problem was related to an incorrectly specified drive letter, the flash drive will become visible and will work in normal mode...

Classes and formats of SD cards

SD-card SD-card is different - they differ not only in volume and manufacturer, but also in size, class (working speed), generation. All this, of course, can affect the visibility of the SD-stick in the card reader...

SD card sizes

There are three form factors of SD cards: SD, miniSD, MicroSD (differ in size). Cards are used in a variety of portable devices: phones, cameras, camcorders, tablets, etc.

The most widely used microSD cards (due to their compact size, they can even be inserted into a miniature phone or MP3 player).

To connect a microSD card to a laptop or computer, it always comes with a small adapter (see photo below).

Typical information on the SD card

Manufacturer : no comments here. The only point is when you buy an SD card for yourself, I recommend choosing well-known manufacturers: SanDisk, Transcend, Sony, etc.

SD card type

SD card type	Description
	Card size: from 128MB to 2GB; Initial file system: FAT16;
SD High Capacity	SDHC card capacity: 4GB to 32GB; Initial file system: FAT32; Since SDHC operates on a different principle than standard SD cards, the new format does not backward compatibility with SD card readers. Note: Card readers released after 2009. must support the SDHC format.
SD Extended Capacity	SDXC capacities from 64 GB to 2 TB (or ~2000 GB); Initial file system: exFAT; Card readers on laptops before 2009 do not support SDXC cards. SDXC cards will work in SDHC compatible (not SD) readers if the computer's operating system supports exFAT (Windows 7, 8, 10).
Ultra High Speed	UHS is an addition to the original SD specification interfaces. When the card and card reader support UHS - will be achieved maximum speed(up to 50MB/s - UHS-50; 104MB/s - UHS-104). AT otherwise, the card reader and card will use the slower, maximum available SD speed. There is no compatibility issue for UHS cards with non-UHS devices.

Important! Compatibility table for card readers and SD card types

In principle, each card reader (on the package with it) indicates which cards it supports. Naturally, if you insert a newer card, he simply will not see it, and you will not be able to read it. The table below will show you the compatibility of card readers and SD card types.

Card reader, phone, camera, etc.	Supported memory cards
SDXC
SDHC
SD

Card class (speed)

Usually, SD cards do not indicate the speed of work (in MB / s, although sometimes they indicate it), but the class of the card. Using the tables below, you can find out what speed your card will support.

👉 Important

The higher the speed, the more expensive the card. Some devices require a specific card class (for example, to the camera, otherwise the video recording will go with brakes, or not at all)- so be careful with this moment!

Speed class

UHS speed class

UHS class	Minimum Speed
1	10MB/s
3	30MB/s

Capacity, card size

The bigger, the better. True, try to proceed from real needs: if you need to store a dozen or two photos, then maybe it makes no sense to overpay and take a high-capacity card?

Lack of drivers

It is possible that your flash drive is not displayed due to the fact that the drivers for the card reader are not installed.

In this case, the card reader itself does not work, which means that it will not read the SD card either. Usually, while the flash drive is not visible in "Disk Management" , and in " Device Manager" - in front of the device will be lit question mark (means there are no drivers).

There is no driver (that's why the flash drive is not displayed ...) - device manager

How to enter device manager

Through the control panel (Windows 7, 8, 10);
Call menu "Run", for this press Win+R and enter devmgmt.msc, press OK.

Look at the tab in Device Manager "USB controllers" it should have something like "Realtek USB 2.0 Card Reader" (see screenshot below 👇). Opposite the device, no question marks or red icons should be lit.

If you do not have a device (card reader) in the lists, and there are unknown devices with question marks (example - ) - most likely you simply do not have a driver.

There are several exits:

In short, this the best way to recover data from an unsupported SD card.

How to recover files from an unsupported SD card

In this part, we will explain in detail how to perform data recovery from compact flash memory. We use a 2GB SD card and Windows 10 as an example.

Step 1 Launch Data Recovery and be sure to insert the SD card into your computer. First, go to the data types area, select the file types by ticking the appropriate checkboxes, such as Image, Video, Audio, etc. Then go to the location area and select the SD card under Removable Devices. After clicking the "Scan" button, data recovery will work automatically.

Step 2. After the standard scan, you will be taken to the results window. And all recoverable files will be saved according to types and formats. Go into each folder and look at them. What's more, the "Filter" function on the top ribbon can quickly find required files. If you can't find the files you want to get back, click the "Deep Scan" button to deep scan your SD card.

Step 3. Finally, select all the files you want on the unsupported SD card and click the "Recover" button to start extracting data to computer. When this is done, you can open, copy and paste or edit the files as usual.

Method 5: Formatting an Unsupported SD Card

After recovering data from an unsupported SD card, you can freely format the card and restore the file system.

Step 1 Insert SD card into Android phone, Windows PC or Mac.

Step 2. On Android phone, go to "Settings" > "Storage", find the "SD card" section and click "Format SD card". Then Android will change the file system to a supported format.

On a Windows PC, go to My Computer, right-click on the SD card in the Portable Devices area, and select Format. Expand the drop-down menu under "File system" and select the appropriate file system:

NTFS is an operating format Windows systems default;

FAT32 is a widely compatible format;

On a Mac, open the Disk Utility app, select an empty SD card under External, and click Erase on the top ribbon. Change the file system of the SD card and click "Erase" again. Now the unsupported SD card should work fine.

Conclusion:

In recent years, the SD card has become widespread in all areas, smartphone owners use it to transfer data, expand memory android phone, save photos in the camera. It makes sense that more and more people are facing SD card related issues. We have shared several ways to fix unsupported SD card error on computer and smartphone.

What to do if Android does not see microSD flash drive? This question often worries owners of smartphones and other gadgets, regardless of manufacturer and cost. The problems of obtaining data from the DVR, installing software on a tablet or smartphone can be solved independently if you know the main causes of the malfunction and how to solve them.

How the problem manifests itself

The malfunction manifests itself as follows: after replacing the “micro-SD” card, after rebooting, flashing or simple inclusion device, the gadget does not see the flash drive or its contents. As a result, data or installed software is lost, the camera and programs begin to write information to internal memory devices. The last one gets hammered fast, place to record service information The OS does not remain and the gadget loses performance and starts to freeze.

As a result, if the internal memory is low, it becomes impossible to work without a memory card.

To fix the problem, you need to establish the causes of the breakdown. Very often it turns out to eliminate the defect with one's own hand, without going to the workshop.

The phone does not see the flash drive due to formatting problems

The partition table can be damaged in any file system (NTFS, ExFat, Fat32). As a result, Android cannot read files written to SD. Most often this happens when the user tries to format the memory card himself and performs incorrect actions. Another option is a card with a different file system is inserted, for example, from a camera. You can restore the card's performance by formatting it again. This can be done either by the phone itself or by another Android device, or by using a computer with a card reader.

The menu of some phones allows you to format the SD card by selecting the appropriate item in the settings. If it is not there, you can reboot the phone, enter the “Recovery” mode and format the file system of the card by selecting “ Wipe cache partition".

Important: errors when working with the device in the “Recovery” mode can lead to the loss of all data and even the inoperability of the OS. Therefore, inexperienced users should not use this method.

It is easier and safer to format flash drives on a computer. To do this, you need a card reader and a formatting program (standard, built into the OS, or any other). It is necessary to remove the flash drive from the device, insert it into the card reader and format it in exFAT or FAT32 format. After formatting, Android should start to “see” the flash drive. If this does not happen, the problem is more serious.

Memory card is out of order

Flash memory has a limited number of read-write cycles. In addition, the device may be damaged due to microcracks in the board or static electricity. In this case, after installation in the card reader, the computer does not detect the flash drive. It is also unreadable on other devices.

It is impossible to recover a damaged memory card or the data on it. This cannot be done either from the Android device itself, or by connecting it to a computer as a USB flash drive, or from a computer via a card reader. It remains only to purchase a new flash card that is compatible with your device.

Important: sometimes, due to a malfunction of the board, phones and tablets can “burn” memory cards. Therefore, if after a short time after replacing the flash drive it fails again, it is necessary to diagnose the android device.

Memory card and android devices are incompatible

A smartphone or tablet may not see a flash card if it is simply not designed to work with modern storage media. When there is a suspicion that the card does not correspond to a tablet or phone, then it is worth trying to read it on a computer with a memory card adapter. If the gadget does not see the card, but the computer sees it, the reason is incompatibility.

All gadgets have limits on maximum size memory cards: 16 GB, 32 GB, 64 GB, 128 GB. This happens if, for example, you bought a 64 GB card, and the limitations of a smartphone (tablet) are 32 GB.

Another option is that the flash drive is made according to a technical specification unknown to your device. In this case, the gadget does not recognize it. Therefore, before buying a memory card, you need to study the documentation of your tablet or phone in order to buy an SD card of the appropriate size and type.

In addition to incompatibility, the device may be damaged or software failure. In this case, the computer will also see the flash card, but the phone (tablet) will not.

Software error

In this case, the gadget either does not see the memory card at all, or certain programs do not see it. If you know that the card is empty, although it shows that the place is occupied, the problem is in the settings or performance of the OS and software of the phone (tablet). If the android does not see the SD card in applications, but sees it in recovery, try looking at the settings first. Perhaps for applications, the save path is set not to the card, but to the internal memory. Fix it.

Another solution when only one application does not see the map is to reinstall or update it, and also check its own settings.

Important: often the phone's OS starts to see the inserted card only after a reboot. If the flash card is not visible without a reboot, and then it works fine, nothing else should be done.

When the above does not help, it is worth trying to update the tablet (phone) firmware. Often, after flashing the OS to a newer version, the device starts to work correctly with the SD card.

Damaged SD card slot

If the smartphone does not see a flash drive installed from another smartphone, while it corresponds technical requirements devices, the problem is in the smartphone itself. In this case, you can try to insert the card so that the contacts in the phone fit snugly into its tracks. To do this, you should try to clean and bend them a little. If it's not about contacts, but about damage to the controller or card slot, it remains to send the gadget for repair or replace it with a new one.

For example, the HTC srochnyi-remont.ru workshop repairs all models of this manufacturer, as well as other brands. Look for a service center for your phone in your city.

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, bypassing the actual memory card. This is inconvenient because the sd card is not being used while the memory of the mobile device 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 causes 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 android versions support this file system.

2. Fast way to fix the problem - 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 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, 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.

The fourth is the SD Formatter utility. Try different file system formats.

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

2. On a Samsung Galaxy A phone 3 memory card not working microsd 16 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.S I 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? The phone may not support this model cards.

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. They sent a congratulatory video. 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 on ebay (flash drive universal i-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 Manage Windows disks and check if the flash drive is mounted when connected to a PC, if the volume is displayed in the list.

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.

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 the 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.

Telephone lenovo vibe shot, android 6. there is a 32gb sony sd card 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.

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.

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 cannot be opened on the computer (i.e., the drive letter / individual drive is not displayed in file manager), it makes sense to check if the memory card is defined 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.

What to do if Android does not see the microSD flash drive? This question often worries owners of smartphones and other gadgets, regardless of manufacturer and cost. The problems of obtaining data from the DVR, installing software on a tablet or smartphone can be solved independently if you know the main causes of the malfunction and how to solve them.

How the problem manifests itself

The malfunction manifests itself as follows: after replacing the micro-SD card, after rebooting, flashing or simply turning on the device, the gadget does not see the flash drive or its contents. As a result, data or installed software is lost, the camera and programs begin to write information to the internal memory of the device. The latter quickly clogs up, there is no place left for recording service information of the OS, and the gadget loses performance and starts to freeze.

As a result, if the internal memory is low, it becomes impossible to work without a memory card.

To fix the problem, you need to establish the causes of the breakdown. Very often it turns out to eliminate the defect with one's own hand, without going to the workshop.

The phone does not see the flash drive due to formatting problems

The partition table can be damaged in any file system (NTFS, ExFat, Fat32). As a result, Android cannot read files written to SD. Most often this happens when the user tries to format the memory card himself and performs incorrect actions. Another option - a card with a different file system is inserted, for example, from a camera. You can restore the card's performance by formatting it again. This can be done either by the phone itself or by another Android device, or by using a computer with a card reader.

Memory card is out of order

Memory card and android devices are incompatible

All gadgets have limitations on the maximum memory card size: 16 GB, 32 GB, 64 GB, 128 GB. This happens if, for example, you bought a 64 GB card, and the limitations of a smartphone (tablet) are 32 GB.

In addition to incompatibility, the device may be damaged or a software failure may occur. In this case, the computer will also see the flash card, but the phone (tablet) will not.

Software error

Another solution when only one application does not see the card is to reinstall or update it, and also check its own settings.

Important: often the phone's OS starts to see the inserted card only after a reboot. If the flash card is not visible without a reboot, and then it works fine, nothing else should be done.

When the above does not help, it is worth trying to update the tablet (phone) firmware. Often, after flashing the OS to a newer version, the device starts to work correctly with the SD card.

Damaged SD card slot

If the smartphone does not see a flash drive installed from another smartphone, while it meets the technical requirements of the device, the problem is in the smartphone itself. In this case, you can try to insert the card so that the contacts in the phone fit snugly into its tracks. To do this, you should try to clean and bend them a little. If it's not about contacts, but about damage to the controller or card slot, it remains to send the gadget for repair or replace it with a new one.

For example, the HTC srochnyi-remont.ru workshop repairs all models of this manufacturer, as well as other brands. Look for a service center for your phone in your city.

Please tell me how to restore the memory card. She just stopped responding at some point, and she was left with wonderful photos.

Sincerely, Mikhail Borisov.

Flash memory made it possible to make drives compact and capacious at the same time. In just a few years, manufacturers have gone from the SD format, 32 × 24 mm in size, to the miniature Micro-SD, 11 × 15 mm. Now such drives can be seen in a laptop, and a tablet, and a smartphone. Therefore, the issues related to them unite today almost all owners of mobile devices. Why can there be data loss on the SD card, and what to do in this case?

Causes of SD card data loss

The SD card is very thin and whimsical electronic device. Therefore, anything can disable it:

Removing the card from the slot at the moment when the device, camera or phone is recording something on it;
A discharge of static electricity from the user's hands at the moment the hands touch the contacts of the flash drive;
Dropping the device;
Sudden shutdown when the battery is completely discharged.

The problem may occur more often if applications have been installed on the card. The probability that the drive was being written to at the time of a power outage or failure is higher in this case. Therefore, smartphone manufacturers recommend installing everything important on the built-in memory of the phone, and storing only photos and music on the SD card.

Methods for recovering an SD memory card and data on it

In the simplest cases, regular scanning by the operating system helps: Android or Windows phone. After scanning, file system errors are automatically corrected. At most, only the last photo or song is lost. At Windows phone 8.1 and higher has its own SD card scanning utility. It starts immediately when the phone starts, if the system suspects errors in the removable drive.

On Android it is recommended to install third party program. One of these is . According to user reviews, it helps a lot.

Recovery using Windows

You can remove the card from your mobile device and scan it using the desktop operating system.

Insert the SD card into the reader and run a normal flash drive scan. To do this, right-click on the shortcut and select properties.

Now you can click the Check and repair SD card button. Errors will be found and corrected.

Format SD card

You can also format the SD card can be formatted. This is also done through the context menu on the right mouse button.

Please note that the format offered by the desktop operating system, does not always match the one used mobile device. After troubleshooting, it is better to format the SD card using the tablet or smartphone itself, in which it is supposed to be used.

SD Formatter

A good solution would be to use the SD Formatter program. It is specifically designed specifically for formatting drives of this type.

This method helps to restore the performance of some models of car navigators.. Errors occurred when writing a large map file larger than 1 GB to a flash drive. After formatting the SD Formatter and rewriting all the files, the navigator started working correctly.

In some cases, special utilities such as EasyRecovery can help in recovering data from an SD card.

Attention! If ChipGenius did not see the flash drive or SD card and it was not read on any device available to you, then all further attempts to revive the drive may be useless.

What to do if the SD card is write-protected?

Another typical failure with drives of this type is the transition to the read-only state. If this happens with an SD card, check the position of the switch on the side. Maybe you switched it to read-only mode yourself, by mistake.

Micro-SD does not have such a switch. Therefore, we are dealing with a controller failure. If the card is branded, then you can look for a special utility from the manufacturer. They are produced for use in service centers. Essentially, these programs reset the controller to initial state, which he received at the factory. Sometimes this way you can bring the drive itself back to life.

If something happens to the SD card, then first of all copy all the files from it to HDD computer or other media! This must be done before any operations with the drive. In the process of working with it with special utilities, you run the risk of forever losing not only the flash drive, but also valuable data on it.

What to do if your SD card keeps crashing

There are only two possible reasons: the drive itself or the device in which you use it. Try replacing the card in your smartphone or tablet with a new one and watch the process. If the failures have stopped, then it is best not to use this capricious drive anymore. At the very important point it will let you down and leave you without important files.

If the smartphone is also unstable with the new media, then there may be a problem with its controller or firmware. Try to find a firmware update for the device and learn from the experience of other users of the device. It is known that old smartphones work unpredictably with cards of new formats with high recording density. Perhaps things will be better with a simpler 16 or 32 GB card.
