    Hello,
    I have a Samsung GT-P3113, running Android 4.2.2. (Samsung Galaxy tab 2. 7.0)
    I have a SanDisk SD card that occasionally messes up, losing files, especially their names. This occurs most frequently when the device is lower on battery (under 30% or so). Also, sometimes the SD card registers as unreadable (intermittent failure). Once, when even my Windows 8 computer could not read it, my Dad was able to back it up with another computer at his work.
    If I use the device to reformat the card, will it perform surface analysis and avoid bad cells when I copy the data back?
    Thanks!

    Nice thing about SanDisk cards - go to SanDisk microSD Tech Support, upper right corner (live chat) and ask for help. They're pretty good. (And when Samsung messed up an update to the S3 that ate cards, SanDisk came out with a modification to their cards to prevent the problem before Samsung came out with an update to fix it.)

    If the card is bad, the shortest warranty is 5 years (some lines go to 10, some go to lifetime), so they'll probably replace it.

    Thanks (I wrote the question), but I still would like to know if Android will scan the card for defects during the reformatting process.
