It's my android phone SD card which was indicated damaged by android yesterday night, out of the blue! I put it directly to a USB port with a USB SD card holder case, so in that way I can recover it with TestDisk, which I had experienced before on a similar situation.

I also noticed that there is a change in file system and capacity:

File System : RAW

Capacity : 0 (unknown capacity)

Also TestDisk doesn't show it on its partitions list. A 2 GB SD card is not that important in price but I've a lot of files and medias which I need them.

Used a mini card reader, TestDisk displayed it on its list but a quick search and or a deep search doesn't have any results No partition found or selected for recovery
and then I should quit the program.

Your help is appreciated.
