If got a 80gig HD for gaming on my Mac Pro. I've installed Age of Conan and it's a huge install. Now I can't defragment this disk in XP. I think this is because there is only 11% of disk space left and when defragmenting XP doesn't have room to move around large files. So my question is; If I re partitioned another large drive to have say, 100mb FAT – could XP use this space to write files to during the defragmenting? Is it possile to partition one drive journaled (OS) and FAT 32 for Windows?
