My SD card is dead. It is a sandisk 32GB model (genuine one as I bought it from a well known seller). All I can see is a partition with 32MB total space. I've tried to recreate the partition table in Gparted but it does no effect (no error either).
The night before I found it spoiled, I used my android phone and plug into Windows, did some files copy/paste to transfer some data between my computers. I dont know what happened but I think my Android phone has spoiled the sd card.
What should I do now?
chckdsk DriveLetter: /fand see if it fixes it? Do this in cmd.exe DriveLetter being the Letter of the SDCard. Make sure you do this in a card reader and not the phone. See if it fixes any drive errors. This will most likely fix it. As I have run the command on several different sd cards that were Currupted or similar to your issue. – NetworkKingPin Apr 01 '16 at 10:39chckdskis not a command. Assuming you meantchkdsk, running that willy-nilly can just as well destroy something permanently. That's why the first step is usually to take a full image of the drive. But in this case it looks like the card (controller, firmware) has failed in such a way that recovery is difficult at best, if not impossible. – Bob Apr 01 '16 at 11:03
