I mean, it's bricked as is anyway, so it can't get *much* worse. Try putting it on a windows system and delete what you can. Then try various tools to mount or reformat the usb stick. I've had a few and I just had to hack at them for a while. It helps if you can remember/determine, how the drive was set up. Fat? Fat32? NTFS? ext3? then test with appropriate tools parted may work, or tell you something about the stick. hth, James Thanks James, no luck with parted either. It'll see the old vfat partition in there, but it will not delete it, reformat it on in any way change it.
