Please help ! my USB won’t function T.T?

ok here is what happend, i used to be using the USB recorded with music to some player that can be played music, then suddenly the item stopped, next thing used to do was apply it to the computer to check on if your files were broken, but when i tried to help open that, a eye-port pops available and pronounces..”F:/ is not accessible.incorrect function.”

i possibly tried to make use of my anti-virus in order to scan it however it is very little use often..T.T you should help me how to proceed..

There are so many possibilities
01 your own USB is usually broken
02 you can try format and then your file will probably be deleted
03 try Norton Partition Magic
04 go–>control panel–>computer management–>storage device–> from there you look at format that.
