I just got my first Mac. Love it. I've been using PC since forever, and I'm used to splitting my harddrive in 2 partitions, a C and a D drive. C for programs, and D for all my personal stuff (pictures, documents, music, video, etc.). This way it's easy to just back up the D-drive, if I wanna do that, or if I wanna install a new Windows or whatever. How do you guys prefer to do it on your Mac? One big partition with some specific backup-procedure, or several partitions etc?
