I had a new 160 GB hard drive installed in my powerbook 15" alum 1.67 GHz powerbook G4. I erased the hard drive that was installed in the powerbook with disk utility to make sure it was clean and installed a fresh version of OS 10.4 on it and started it up. I have a clone of the original Hard drive on an external fire wire and I had the old hard drive put into a USB 2.0 external box. I also have a clone of the powerbooks old hard drive on a 60GB partition on my desktop hard drive. My problem is the external firewire and usb drives will not mount on the powerbook now. The external firewire mounts onto the desktop fine, and I can actually access it and mount it on my powerbook via my ethernet network. I can do the same with the original drive in the usb box but can not hook any of them up directly to the powerbook. I tried starting the powerbook up in target disk mode but the desktop would not recognize it. Can I try to clone the external firewire to the powerbook, via the ethernet network? It seems to me that you can not clone another hard drive to the computer you are actually using the initiate the clone or am I wrong?
