I have a 32GB flash drive that I want to use as a Mac OS X boot drive for intel Macs, but I'd also like to have a small FAT32 partition on it (just for data, doesn't need to boot Windows). Since it has to boot Intel macs, it has to be partitioned with the GUID scheme. While the Mac can format a partition as Fat32, Windows boxes won't usually recognize it. I've tried to format and partition on a Windows box, but haven't any additional luck on that side (windows doesn't seem to like the GUID partition scheme and can only format the first partition (a 200MB partition used for the EFI system partition)). Any advice?
