Hello! I just got a new 15" Powerbook, which so far has been an amazing machine. I do quite a lot of graphic/web design and so like to backup my files often. I guess my question is this; is there a way to use one firewire external HDD to backup two different computers? Basically, I would want to backup my G5 onto one partition, and my Powerbook onto another. I currently use and love SuperDuper! to backup my files. Thanks a ton.
