Was this a internal flash drive or SSD? Or was it one of those USB drives that you can dangle off your keychain?
If it's one of the USB drives then it's gone man, sorry.
USB Jump/Flash drives are notorious for corrupting themselves out of the blue for no reason at all. Try not to store important stuff on them =O
