HI my usb just really suddenly broke. it is now not showing up or being registered by any computer at all. I have checked in device manager and its not there. another thing is that after about a minute it get very very hot. What do i do? there is important work on it
Then it's probably shot. =( That's why you should just back up your stuff online.
Simply backup all the file from your USB and then try to Format it.
Go to my Computer and look for the removable drive, if it shows.
Then right click on the drive and select Format.
