I just purchased two 2TB Western Digital MyBook Studio hard drives (from Apple) to store raw video content on. We have one Mac Pro for video editing but the rest of the office uses Windows XP. How can I format these hard drives so they will be accessible on both OS10.4 and Windows XP? We want the full 2TB of each HD to be in one partition. Should I do the formatting on the Mac or on the PC? Any help would be appreciated.
