I have a PowerMac G5 and an external USB 2.0 hard drive. I have all my info cloned on the external drive including OS 10.4.2. The PowerMac only has 10.3.9 and I can't find my Tiger DVD. The external will not work as a bootable HD for some reason even tho it was set to be bootable by Carbon Copy Cloner. Is there a program that will allow me to make an exact copy of that drive to the drive in the PM G5? For example, a program that does the copy before the OS boots so I can overwrite it. I can't make the external drive internal becuase it is ATA/133 and the other drive is SATA. Got any ideas or any ideas on how to make the external drive bootable? Thanks all.
