GO TO disk control panel goto administrative tools go to computer management go to disk management find the letter of your flash drive low level format it under FAT32 BAM! you have it back whatever you had on your flash drive is gone. if you can't read your flash drive and you haven't tried my fix, assume your data is lost. you can try a tool like PC inspector smart recovery, but if your computer recognizes your flash drive, yet won't access it, your data is gone. An easy way this happens is: 1. You formatted the flash drive by accident thinking it was another hard disk. (Always remove flash drives when partitioning other hard disks.) 2. You failed to STOP the flash drive before removing it and the flash drive became corrupted.
