I have this drive: http://www.seagate.com/www/en-gb/products/external/freeagent/freeagent_go/ which says on it "Auto backup, encrypt and sync software for PC".There is also a Mac version here: http://www.seagate.com/www/en-us/products/external/freeagent/freeagent_go_mac/ I don't have my mac yet, it's on it's way. I wanted to know if I can just use my current 'for pc' drive in my mac if I connect it up and format it? I can't tell if the difference between the pc and mac versions is just to do with how they are pre formatted and the software that comes with them, or if i can just format the pc version with my mac and use that. Basically, I just want my music and videos on a portable drive that I can move between my mac and pc. Is there a better way?
