My DT50 16gb usb 3.0... i tried everything but no solution

Hello,

unfortunatelly i had the same problem with my DT50 16gb usb 3.0... i tried everything but no solution.... i asked a friend of mine and he said that my usb was dead.. it burned unfortunatelly. When you can't get any solution (from all this methods cmd etc., that you tried) this means that was burned and he said that when the usb was burned you can see your files on your usb but you can't copy, transfer, delete or do any format.
