Hey Folks, My Dad has a PowerMac G4 400MHz Sawtooth. It has a 10GB Hard Drive in it. He wants to upgrade up to Jaguar. I've already installed a Radeon Mac Edition video card to take advantage of Quartz Extreme. I have a 40GB IBM Deskstar 120GXP hard drive coming in the mail. I want to install Jaguar on the new hard drive, copy his files from the old hard drive over to the new one, and then turn around and reformat the old 10GB drive. I want to make the 10GB hard drive a backup drive that periodically copies the user directory in Jaguar on the new 40GB drive. This is what I am thinking, and you guys can correct me if I am wrong... 1. Take out the old drive and replace it with the 40GB drive. 2. Boot up the computer from the Jaguar installation disk. 3. Reformat the new 40GB drive and install Jaguar. 4. Run software update. 5. Install the old hard drive in the slot above the new drive. 6. Boot up Jaguar, and copy the appropriate files from the old drive to the new one. 7. Use Disk Utiity to reformat the old 10GB drive. So, I'm wondering what problems to anticipate. Since the current configuration only has one hard drive, and I want my new hard drive to be the main disk, will I have to switch any jumpers to make the old disk a slave to the new master disk? Will I have to mount the new drive into the lower slot where the current drive is, and then mount the current drive above the new one? Also, does anybody know of a good utility to set up an automatic backup of the user directory to be copied to the backup drive? Thanks very much for your help.
