I have a flash drive that I used not too much but, after few month of inactivity, it died. I know that flash drives have a limited write cycles but I am sure that this is not the problem.

I tried to create a new partition table and format the drive nothing worked. This is the output of mkfs.ext2.

Is there something I can do to recover it?

Recover the Data or recover it for continued use? – Moab Jan 9 '11 at 17:00
@Moab: I wanna recover my drive as I like it – mg. Jan 9 '11 at 19:02

Try seeing if it has a backup super block that you can use to repair it.

There is a good article here that could give you some ideas (It's on ext3, not sure if it will work on ext2).

Try this to see if you have a chance of it working:

$ dumpe2fs /dev/sdc1 | grep superblock

Thank you Dan but I tried ext2 because maybe linux tools handle better this filesystem type but originally the partition was formatted as fat32 – mg. Jan 9 '11 at 19:08

It seems the drive died definitely. I can not format it with any tool I tried.
