Micro sd card formats but reverts to normal after remount

[Jovica Lalic]

I partitioned my sd card through clockworkmod recovery on my xperia mini and at first it seemed to work great. It wasnt the first time I partitioned it, and it wasnt the first sd card I partitioned. It has 3 partitions:
fat32: 10.66 GB;
ext4: 3.81 GB
and swap: 244.60 MB
I managed to copy a zip file to it (rom) but after that i couldn copy anything else,nor delete the file. I tried to format it through my phone,and through a laptop with an sd card reader,with no luck. I used sd formatter, many partition software and windows disk managment with no luck.
Also tried it on linux,through terminal,with gparted and disks,but it didnt work. I can use it in my phone, but after i unmount it and mount it again my files are deleted and the zip file is back even after deleting it.Any help would be apreciated.

My guess would be the SD card has died.

Well its only about a year old.

Doesn't make any difference. There is a wide range of qualities across the SD cards. Not to mention it is an item that has limited write cycles anyways.

I've had a couple now fail essentially in the manner you describe. I'd bet if you try a new card, all your problems go away. Also note, since you probably can't erase anything at this point, I would destroy the SD card before you get rid of it if you had any personal data on it.
