My girlfriend and I use different laptops- I, PowerBook; she, HP. We're trying to come up with a way where we can share files (we live in two different houses) using my external hdd as the middle man. Obviously, she can't read the disk (HFS Journaled) without shareware. I heard somewhere a while ago that OS X can read/write to FAT partitions as can Windows XP. Have any of you ever done this? What do you think? I would still like the drive to be perusable with Spotlight, but if it can't be, it's no problem. What are your thoughts?
