The sd card is damaged, at first it works, and after a while the phone considers it damaged. Why the phone does not see the SD or microSD memory card - all solutions Micro sd turns off
Hello Oleg! There are many options for your situation. For example, the card may be defective or physically damaged (this will not necessarily be visible from the outside). Let's look at the options.
Checking the card with special programs
Checking the card in another phone or device
It is likely that the problem is not with the card, but with your phone. Accordingly, you need to try 3 options:
- insert your card into another phone and check its operation there;
- take another card from friends or colleagues and see how the phone will behave with it;
- do full reset devices to factory settings. How to do it right - read our article. Do not forget before resetting important data - during the recovery process, all of them will be deleted.
If the problems repeat in another phone and your SD card is still under warranty, change it or return the money. Of course, for this you need to find the documents for the purchase. If the card is not under warranty or the documents are lost, all you have to do is purchase new card. But, be sure to make sure before that that the problem is in the card, and not in the phone - do a full reset of the device according to the instructions above. Otherwise, the problem may recur with a new SD card.

Having problems on an android phone or any other with a memory card? Can't read data from it or your android phone/tablet doesn't detect it?
You can repair a damaged micro sd card if it is damaged using a computer, check it for errors, or completely reformat it.
In general, the fact that the SD card is not read is not unusual. If you have a lot of data stored on it and use it extensively on your phone, there is always a chance that you might have a problem reading the content.
But this does not mean that the card should be discarded immediately. There is always a chance to restore the work of the SD card.
If you fail to fix the memory card, then the files located on damaged card memory can be restored -
Sometimes the solution may be to check the file system for errors in saved files, repair bad sectors, format the card, or complete removal section (map structure) and its re-creation. Let's take a look at each of these solutions below.
How can I restore the performance of an external sd card
To fix a damaged sd card you will need:
- PC or laptop running Windows;
- any way to connect an SD card directly to a computer.
You can connect it to your computer with an adapter - if not, you can buy a USB card reader.
Method One - Repairing a Corrupted CHKDSK File System
If your device says sd card is damaged, here's what you can do. The first and easiest way is to use the Windows recovery tool system disk, i.e. CHDSK.
This tool is from Microsoft and is only available on Windows computers. CHKDSK does this without deleting any files, so you won't lose card data.
First, connect the SD card directly to your computer or laptop and launch My Computer or This PC (Windows 8 and later).
In the drive list, find the included SD card and remember which drive letter it was assigned to. For the purposes of this guide, let's assume that the card has been assigned the letter "D".
Press combination Windows keys+ R to bring up a window Windows startup. In the run window, enter the following command to enable command line: cmd.
A new command line window will appear. Now you must enter the appropriate command, which will scan the memory card and fix errors on it. The command looks like this:
Chkdsk D: /f
Of course, instead of "D:", write your drive letter (don't forget the colon). Press the "Enter" button to start scanning.
After the scan, you can test your memory drive and see if everything works.
Method two - formatting a damaged sd card
The second way to fix a damaged SD card is to format it and delete all data. This option can help if CHKDSK was unable to verify and there are still problems (for example, errors reading individual files).
Of course, you will lose all data, but chances are that formatting will fix the card.
To do this, connect the drive to your computer, and then call "My Computer" or "This Computer". Find the connected SD card in the disk list and right-click it.
Select "Format" in context menu. A new format window will appear for the specified drive (in this case, the SD card).
Click the "Default Allocation Size" button and make sure "FAT32" is selected as the file system.
You can format with the "Quick Format" option selected, only for more accurate results I recommend that you uncheck this box - the formatting will be much longer, but done more carefully, which can help solve problems with the card.
After formatting, reinsert the card into your smartphone, tablet, digital camera or other device you are using and make sure the card is working properly.
Method three - completely delete all partitions and re-create again
An SD card is no different from a regular disk - it can have one or more partitions. By default, there is always only one section.
You can format the card in such a way as to completely remove the partition and leave it unallocated.
This is called low-level formatting. Note that this will also permanently delete all data on the memory card.
After formatting, you can create a new partition. This often helps when the memory card appears as "RAW" after plugging in and doesn't show partitions that can be accessed.
For this formatting, you can use a program called "HDD Low Level Format Tool". You can download below.
Connect the drive to your computer and then run the Low Level Detection Tool hard drive.
See a list of all your drives on your computer, including the connected one external drive. Find your SD card in the list and select it.
Make sure you choose the right one. Once selected, click Continue and go to the Format this device tab.
The card will be completely formatted and all partitions will be deleted. This will now be a clean, unallocated surface.
That's not all - the card is in such a state that it will be useless. Now go to the start menu and find the Tools folder Windows administration”, and in it select “Computer Management”.
A new window will appear. In it, select "Disk Management". A new window will appear displaying all drives - both internal and external connected via USB.
Find your drive, the surface of which is displayed in black. Right-click on the black unallocated area and select New Simple Volume.
You will see a wizard that will guide you step by step through the partition creation process. You don't need to change anything, just click next. Pay attention to the "File system" field and make sure that FAT32 is selected instead of NTFS.
Confirm the creation of a new partition. Your micro sd card will now appear in the My Computer window with a drive letter automatically assigned. You can disconnect it from your computer and connect it to your phone or tablet. Good luck.

Support external cards memory for many Android users is an important criterion when choosing a new device. Fortunately, most of them still support this option. However, failures can also occur here - for example, a message about damage to the SD card. Today you will learn why this error occurs and how to deal with it.
The message "SD card is not working" or " Empty SD card: formatting required" may appear in the following cases:
Reason 1: Random single failure
Alas, the nature of Android is such that it is impossible to test its operation on absolutely all devices, therefore, errors and failures occur. Perhaps you moved applications to a USB flash drive, for some reason it crashed, and as a result, the OS did not detect external media. In fact, there can be many such reasons, but almost all random failures are fixed by rebooting the device.
Reason 2: Poor contact between slot and memory card
A portable device such as a phone or tablet is subject to stress during operation, even when in a pocket or bag. As a result, movable elements, which include the memory card, can move in their grooves. Therefore, if you encounter an error about a damaged flash drive that cannot be corrected by a reboot, you should remove the card from the device and inspect it; it is also possible that the contacts are contaminated with dust, which in any case penetrates into the device. Contacts, by the way, can be wiped with alcohol wipes.
If the contacts on the memory card itself are visually clean, you can just wait a while and insert it again - perhaps the device or the flash drive itself has simply warmed up. After a while, put the SD card back in and make sure it's fully seated (but don't overdo it!). If the problem was in poor contact, after these manipulations it will disappear. If the problem persists, read on.
Reason 3: The presence of bad sectors in the map file table
The problem most often faced by fans of connecting the device to a PC and instead of safely removing it, simply pull out the cord. However, no one is immune from this: this can cause an OS crash (for example, shutdowns when the battery is low or an emergency reboot) or even a banal file transfer (copy or Ctrl + X) using the phone itself. The owners of cards with the FAT32 file system are also at risk.
As a rule, a message about an erroneous recognition of an SD card is preceded by other unpleasant symptoms: files from such a flash drive are read with errors, files disappear altogether, or such digital ghosts appear. Naturally, neither a reboot nor an attempt to pull out and insert a USB flash drive will fix the cause of this behavior. In such a situation, you should act like this:

Reason 4: Physical damage to the card
Most bad option development of events - the flash drive was damaged mechanically or upon contact with water, fire. In this case, we are powerless - most likely, data from such a card cannot be recovered, and you have no choice but to throw away the old SD card and purchase a new one.
The error, accompanied by a message about the damage to the memory card, is one of the most annoying that can happen to users of devices under Android control. Fortunately, in most cases this is just a single failure.
