I'm looking to upgrade my PowerMac G4's 40GB drive to a 120GB that's just been freed up in the office. For various reasons, I'm not interested in simply adding the 120GB as a second drive -- I want to transfer the entire contents of the 40 to the 120 and have it run as before. I know there are apps that can perform this transfer, but I'm interested in using the built in capabilities of OSX instead. Is there a safe, reliable way to do this using DiskUtility? I do recall one occasion in which I was unable to install Tiger on an older PowerMac that couldn't read DVDs, so I used DiskUtility to transfer the bootable image of the Tiger DVD to a small external firewire drive, and was able to install that way. Could it be that simple for transferring an entire drive too?
