My little brother has borrowed a Sandisk Cruzer 16GB from a friend. He thought he’d better clean it well before giving it back to his friend and deleted some u3 file he didn’t know was important. Now whenever we plug the usb device in a Windows 7 pc we get the message “USB Device not Recognized”, there’s no storable drive we can detect anymore. (Tried it on 2 different Windows 7 machines)
Is there a way we can fix this?
Edit: Also tried this: http://kb.sandisk.com/app/answers/detail/a_id/10 but didn’t work either.
