I would like some suggestions on a good firewire hard drive that's portable in the sense that I can throw it in a bag and take it to a Mac lab at my college. I'm looking for something in the 60Gb to 80Gb range and a spindle speed of 7200RPM. Questions: 1) The Macs at my college are running OS 9 and I run OS 10 at home. Do I need to format the drive for OS 9? Is there a performance or reliability hit by doing so? 2) Do I need to install software on a Mac at my school before I can use the drive? I hoping it will just see it as a "regular" drive without any problems. 3) I'm not sure of the networking configuration at my school but could someone have access to my drive when it's hooked up to the Mac that I'm using at my school's lab? Thanks for your time.
