[QUOTE="chscag, post: 1100142, member: 46727"] @lifeisabeach Step 7 of that tutorial is the key. The problem occurs when folks use Disk Utility to format a flash drive or USB external drive to FAT-32. The default partitioning scheme is GUID; unless OPTIONS is selected and the MBR choice is made, the result will be two partitions: 1. EFI 200 MB 2. The remainder of the drive space. Windows refuses to "see" past the first partition on external devices and therefore reports the drive as 200 MB rather then its full size. The only way to clear the drive and set it right is to use DISKPART from a command prompt in Windows and do an erase. That isn't working for the OP. We've tried several times. For some reason the media drive he has won't show up in DISKPART but does show up in My Computer. It's a real head scratcher. :\ Regards. [/QUOTE]
