I have a MacBook with Mac OS X (of course) and Bootcamp with Windows XP. I'm buying an external firewire hard drive 320 gigs, and I want 2 paritions. 160gigs for NTFS (windows) and 160 gigs of the Mac file system. I am not asking to boot Windows off of the external drive. I'm thinking of using parition magic on windows to make 160 gigs NFTS, and then booting into Mac and using disk utility to format the remaining free space on the drive as Mac file system. Will this work, or is there a better/easier way of doing this? Is it even possible?
