[OT]usb stick

[L . V . Gandhi]

I have Transend usb pen drive. It was working OK. I gave to my nephew for backup. He used in some other PC. Now it is not working. Now when I insert nothing happens. I mean no message in syslog.
But in the same machine with other USB stick I get as

What might have gone wrong with that non-working drive? How to make it usable?
