I'm running a PowerBook which obviously has a slow hard drive, so I've got a 7200rpm 120gb firewire drive on the way to me now. I was thinking of using the Firewire drive as my "docked" boot HD and then the PowerBook one when I need portability. I was thinking of using CarbonCopyCloner to do this. Will this work? And will using the firewire drive speed things up for me this way?
