Expand free place on the internal storage quite simply using a mircoSD format memory card. But the disadvantage of SSDs is the limited resource of work, as a result of which they quite often fail. Let's consider in what situations the SD card can be damaged by android and how to fix this problem.
You can transfer data from a damaged memory card without formatting in some cases with using USB Card Reader with microSD support. Such a device can be purchased at almost any computer hardware store.
Memory card does not appear in Android file manager
No data on memory card
Also, it is no larger than a regular USB flash drive, and therefore it can always be carried with you.
Action algorithm
So, if the flash drive does not open on the phone and there is a computer at hand, as well as a USB Card Reader, then you can start data recovery. To do this, follow these steps in sequence:
- Turn off mobile phone or tablet.
- Remove the back cover and battery (if necessary), and then carefully remove the microSD memory card from your slot. You can find out exactly where the flash drive is in your device model by going to the official website of the developer. An alternative would be to view the information you need from reviews on the Internet.
- Insert the USB flash drive into the USB Card Reader and connect the device to the PC.
- If the data of the memory card is displayed on the computer screen, then copy all its contents to hDD.
After copying information from a memory card, it is worth formatting it. With a high degree of probability, now the flash drive will open in your mobile device. For more information about the device for reading a microSD memory card on a computer, see the training video.
Outdated file system
Modern smartphone models support memory cards of various file systems, including exFAT, NTFS and FAT32. The last one is more outdated and quite often the problem with reading a flash drive on phones is precisely in its use. In addition, if you watch high-quality films on your mobile phone, then FAT32 will definitely not suit you. Indeed, it is impossible to reset a file larger than 4 GB on such a USB flash drive. The rest of the advantages of file nTFS systems Relate to higher reliability and fault tolerance during active operation.
Action algorithm
Fix damage microSD cards Android due to an outdated file system is not so simple. The thing is, do it standard way By default, the computer’s OS will fail. Well-known utilities designed for formatting will not cope with the task disk drives, PartitionMagic and the like. But still, using the device manager or a special program, you can change the file system and “revive” the damaged flash drive. True, in this case, it is advisable to take care of backing up data from it to a computer or other drive in advance, since the recovery procedure involves formatting the medium.

If SD is used for important files, you need to back up your personal information as often as possible. Frequent reserve copy guarantees the elimination of unnecessary risks for existing files.
What to do if a sector is damaged on a memory card?
The memory card may be damaged due to a violation of a sector.In this case, repair measures are recommended. How to act?
- The memory card must be removed from the smartphone and installed in a computer reader.
- Now you need to go into My computer and find the memory card of interest.
- You should click on the icon with the right button of a computer mouse and open “Properties”.
- At the next stage, go to the “Service” tab and to the “Check the disk for errors” section.
- Item “Check and restore bad sectors»Will improve the condition of the memory card.
- After a successfully completed check, you need to make sure the memory card is working using it on the phone.
It’s important to remember: formatting in the classic way is the most extreme measure. In this case, any information will be destroyed and will fail.
Choosing the right memory card based on factory requirements android smartphone and its careful use can successfully prevent numerous risks.
Almost every modern person has several portable devices (smartphone, tablet, camera), where Micro SD or SD card is used as a drive. Information stored in this way is often lost, including through the fault of the user.
Storing photos or videos only on the phone (tablet, camera) is fraught with consequences: there is a danger that the data will be accidentally erased.
The main rule is never store important files only on memory cards. Do backups data on the hard drive, flash drive, cloud storage etc.
But if a terrible thing happened, and the necessary information was deleted, there is still a chance to fix it: microsd recovery it is possible to produce at home using special software, even if file system flash drives will be damaged.
When is recovery possible?
Recovery of SD and Micro SD is possible if a little time has passed since the deletion of the files and the data has not been overwritten. Return deleted information You can even after formatting - if it was fast, not deep.
Some files are recovered after deep formatting, but using free software is difficult to do - it can only help if you contact a specialized center whose specialists are involved in recovering deleted data.
Recovery through R-Undelete
Let's see how to restore a memory card if you accidentally deleted it needed files or started quick formatting without first moving the data to another medium.
When working with SD and Micro SD, the same rule applies as with other media - as soon as you find that the necessary files on the phone (tablet, camera) are deleted, immediately stop working and remove the drive from the device.
Let's try to recover information from the Micro SD card using the R-Undelete program. It can be used to return deleted data from a flash drive, hard drive and other drives except CD and DVD.
After the Micro SD card scan is completed, a report of the found files will appear. It displays all the data, both existing and deleted. You can select photos, videos and other files one at a time or restore entire folders at once. 
The program has a preview function: double-clicking on the photo, you can see if this is the picture that you need. If the file does not open, then it is unlikely to be restored. But most of the data is returned intact - you just have to specify a place to save it.
Do not use the Micro SD card with which data was restored to save the information found. Better discard the information on a USB flash drive or hard drive; then transfer where you see fit.
After clicking the “Recover” button, file recovery will begin. In the process of returning deleted data, windows will appear to notify you of an error in the file name. To fix this problem, check “Replace damaged characters with” and indicate “$”. All invalid characters in the file names will be replaced with the “$” sign, which will avoid problems with data recovery. Similarly, you can restore photos and other files from a micro USB flash drive using the utilities Recuva, DMDE, R.Saver, etc.
File system damaged
If the files were deleted as a result of damage to the flash drive or memory card, then recovering them will be somewhat more difficult. We also include deep formatting, in which the source information is sometimes so overwritten that it becomes almost impossible to read it. 
If Recuva or DMDE is unable to complete the task and cannot return the memory card to workable state or at least restore a photo after deep formatting, the use of R-Undelete gives some chances for a positive outcome. The secret is that even formatted and partially overwritten files can be found by signatures, which we will do:
- Launch R-Undelete and select the connected media with photos or other necessary files. If the memory card is so damaged that it is not detected by the system, select the letter of the card reader itself.
- Check the box that starts the in-depth file search.
- To indicate what kind of information should be restored in the first place, check the box “Search for files of known types” and click “Known types”. Select the desired format (if it is a photo, but it will be * .jpg or * .raw).
Choosing a specific format, you increase the chances of finding and restoring the necessary information. If you need all the files that were on the media, then you can not select any formats.
After selecting the scanning mode, the search for the selected data will start (a rather lengthy procedure). The scan results will be presented in a list. You just have to select the necessary files and click "Next" to go to the window for setting recovery options. 
Be sure to check the “Advanced Found Files” folder. If the memory card was working at zero, then in this directory you will find many corrupted files and the changed name. Remember: if the preview function does not work, then the file cannot be restored, so you can not even mark it.
When choosing a directory for saving files found, specify any other medium except the memory card itself. If during the recovery process a message appears stating that the file name is damaged, then you need to check “Replace damaged characters with” and set the “$” symbol to replace the missing item.
Today, a very large part of the mass models of digital cameras rely on SD-memory cards as the main means for recording photos and videos. The formats in which data is stored on them vary depending on the make and model of the camera, but, as a rule, are based on a similar organizational structure, which, however, is not completely immune from errors and malfunctions. That is why in many manuals, manufacturers emphasize that in order to avoid the risk of information damage, the memory card should only be removed or inserted into the device when it is turned off.
However, many users ignore this warning and get a bunch of spoiled photos, and with them very unpleasant emotions. However, improper handling of the SD card is far from the only cause of such problems. It is not uncommon for damage to occur when the camera is completely discharged directly during the shooting process, and sometimes flash cards fail without any apparent reasons. As a result, upon returning home after a holiday, instead of hundreds of digitally captured memories, the owner of the camera discovers a memory filled with unreadable files. Fortunately, not everything is lost - data on a seemingly unusable memory card can often be restored. Here is how.
Necessary tools
Although on the Internet you can find many guides to recover information from damaged sd cards, in this text I will proceed from three basic assumptions: you are a Windows user, you are not a technology expert and do not have extra time to read and study numerous instructions.
I want to offer you a very fast and easy to use solution - a small but very useful program called ZAR X Systems recovery software. Though full version the tool is paid, the recovery tool (which we actually need) is available absolutely free in the demo version.
After downloading and installing the program, make sure that you have enough space on local drive to save the data recovered from the memory card. This means that if your card is 16 GB, then you should have about 16 GB of free space on your computer’s hard drive. You will also need a card reader (in other words, a card reader) - most modern laptops have a built-in slot.
Recovery
I do not recommend that if you find that the entries on the memory card are damaged and are not recognized correctly, try to copy or rename them manually. Instead, trust the tool. Connect the memory card, launch ZAR X and select “Image Recovery” - the option is available in free version applications.
For the average smartphone user, the data stored on the phone and the memory card is more important than the device itself. Therefore, when a microSD drive is damaged, people are more afraid for the safety of data than for the performance of a flash drive. So, we’ll look at how to fix the damage to the SD card on Android and restore the data.
Causes of Damage
Nothing is eternal. This statement is true for removable media. Perhaps your card has exhausted its resource and moved into another world. But there are still a number of reasons that cause a similar problem:
- Error in smartphone OS. Invisible processes of Android or any other mobile operating system more or less often lead to errors that leave a certain imprint on the performance of flash memory.
- Outdated file system. If your SD card uses FAT, this can lead to errors, as Some modern applications no longer work with this standard and do not properly interact with the device.
- Emergency shutdown of data transmission. If you turn off the phone while copying files from a PC to the phone’s flash memory USB cable, with a probability of more than 50% damage to the SD card is irreversible.
Attention! Never disconnect the device before the end of the data transfer process. Cancel the operation if necessary!
- Incorrect drive removal. If you remove the flash drive without first disconnecting it, there is a risk of data corruption and loss of functionality of the SD card.
Solution
To restore data and treat a flash drive, follow these steps:
But there are situations when the memory card does not open on the computer. This is a bad sign and in this case you should turn to third-party data recovery utilities.
To do this, you need:
The above steps will help return some of the valuable information.
Advice! To prevent such situations, it is recommended that you regularly back up important files!
If the removable media is not detected by the computer, it will not be possible to independently access data without certain skills and resources. Therefore, if necessary, contact a service center for the repair of removable media. Now you know how to fix SD card damage on Android.
