Ok, so I need to format my USB to FAT32 so I can access all of it and not just 2GB. When I install it and click the Format Options I get FAT, ext2, ext4 and encrypted FAT. Using Disk Utility I looked at a USB disk that I formatted "FAT" and it said it was 32bit(FAT32?) so I should be able to use all 8MB of volume for stuff, right?
