[QUOTE="chscag, post: 1099603, member: 46727"] Common problem when using Disk Utility to either format or partition a flash drive. Long story involved. Short story: Don't use Disk Utility unless you know how to format the flash drive without creating an EFI 200 MB partition. Anyway, here's how to resolve it: You'll need a working PC with Windows to do it or a dual boot Mac with Windows. (Can not use OS X) Follow the instructions given at this [URL="http://pitumbo.com/how-delete-gpt-partition-or-efi-mac-hard-disks-vista-or-xp"]LINK[/URL] carefully. Read them first and make sure you understand what's being done before doing it. Regards. [/QUOTE]
