So I have a powerbook g4 that has mac os X 10.4 on it. I have backed up everything on a monthly basis. I want to upgrade the 100 gb hard drive to a 320 or a bit bigger. From what I see I can just use my "superduper" program and copy the backup to the new hard drive shut it down install the new one and everything should be good to go. Or the other option I think I have is to install the newer version mac os X 10.4 which I can get. So which way should I go an installing the new HD?
