Format: and a few other things. Now choose
Erase. This should give you *Volume Format:* and
Name:. Click on the *Volume Format:* and choose *MS-DOS File System* and then pick the
Erase button. This should erase and format the flash drive to FAT 32. If this doesn't work you may need to use a PC to reformat the Flash Drive to FAT 32.
