When your Micro SD card is corrupted or damaged, you should first do a check disk error within an MS Windows chkdsk command prompt. It can help you fix the corrupted SD card file system and make the card accessible. And during the process, all your files will keep intact.
1. Plug in your SD card to your computer with a card reader.
2. Go to the start menu, type in: cmd in a search bar, hit enter and then you can see something named "cmd. exe" under a list of programs.
3. Right-click "cmd. exe" and then you will get the following command windows that allow you to fix your corrupted SD card without format.
4. Type in: chkdsk /X /f sd card letter: or chkdsk sd card letter: /f, for example "chkdsk /X /f G:" or "chkdsk h: /f".
After all the steps, Windows will check and fix the corrupted SD card file system. It usually takes several minutes. After that, if you see "Windows has made corrections to the file system" in the command window, then congratulations!
