/home/user/MyDocs corrupted. help please.

I cannot find the partition from USB storage mode on my Linux. Tried Testdisk to recover some photos but it failed to determine the FAT32 partition.

However, I can use some of the data in the partition.

I don't know what happened. even

df -h

do not have the /home/user/MyDocs


Found a similar thread but it require format the disk... ok. since testdisk failure, I don't hold any hope to recover...
