I am upgrading hard drives in my PowerBook G4 from a 80 Gb to a 240 Gb and I do not want to lose any of my information how do I duplicate the info from my 80 Gb to the new hard drive. What I was thinking about doing was firewire my Powerbook with the 80 gb hard drive in it to my imac and copy and paste the entire harddrive into the desktop then put the new hd in my mac firewire it again then format the hdd using the imac then drop and drag the info from the old hdd into the new one would this work?
