I have a Firewire Drive that I use to backup my G4 Powermac using CCC. It currently has (1) partition and half the drive is free space. I just got a new iBook and I want to back that up also. Do I have to create/maintain a seperate partition for the iBook image or can i use the same one that I currently use for the Powermac provided there is enough free space? I'm guessing seperate partitions are needed.
