I just used Carbon Copy Cloner to backup my G4 PowerBook hard drive. I'm down to just a few gigs and it's been going really slow. I'm still running 10.3.9 too. Basically, I want to get this computer running as new with all the necessary updates. It's a 1.33 GHz PowerPC G4 with 768 ram. Should I reformat the drive and then install a more recent OSX? Any recommendations? Also, a quick question about my backup. I noticed all the files that are backed up to the external drive are about a gig short from the amount of space used on my Mac's hard drive. Is that right? I've gotten this far with backing up another drive and my mac's drive to my new external hard drive with all your help, so thanks!
