 A computer has more than one disk socket, a SanDisk USB drive interface does not work, it may be this USB port is broken. So you can try to insert other USB interfaces to see if the error disappears. If the error still exists, it means that there is a problem with the SanDisk USB drive.

 To sum up, when you encounter a SanDisk USB drive that won't open prompting a formatting problem, don't panic and don't format the drive.
