Hello!

I have faced a problem with my SD card and formatted it in accordance with your instruction. But now, how can I check, whether the card is not damaged and fully operational? Are there any methods or programs for SD cards checking?

Thank you!

Good day to you!
There are two reasons for SD memory card errors: program errors of Android operating system or hardware errors (errors of the SD card itself). After having recovered your SD card, (article: SD Card Recovery: how to fix damaged SD Card), be sure to check it for errors before inserting it back in your phone.

SD cards testing by the means of Windows (instruction):

1. Insert an SD card in card reader and connect it to USB-connector of your computer, you will see it in Windows Explorer like an ordinary disk:

2. Click your SD card with the right mouse button and select “Properties” in the menu:

3. In an opened window, proceed to “Tools” tab and press “Check now” button:

4. In a new window, tick “Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors”, then click “Start” button:

5. SD card checking may take several minutes, after that you will see a window, containing a report:

SD card checking may take several minutes


There are no errors in our case. If there will be any – they will be mentioned in the report. 
 

Windows will attempt to fix all the found errors, but if there are any errors of sectors, it’s worth considering buying a new SD card, they are very cheap nowadays.
 

Please note: Successful Windows checking doesn’t always guarantee that the card operates normally and won’t break down any time soon. It’s recommended to check it with h2testw program (article: (not available))
