I am in the market for a 160+ Firewire hard drive. When I ship off to college next year, it would be insanely great if I could plug the drive into a friend's PC to swap files, but my brief attempt to do so with a Lacie drive failed to mount on the PC (for obvious reasons; the drive was designed for Macintosh and formated HFS+). If I buy the right drive, can I possibly achieve my desired file sharing by formating the drive FAT or something? What do I need to know? Your input is greatly appreciated.
