Another consideration in using ATA drives in a new dual core PowerMac is that the PCIe (Extreme?) is NOT backward compatible with any PCI cards, so you'll need to find a PCIe card for your G4 drives. I'd go USB or Firewire. I'm getting another 250GB drive and keeping my MDD's 2 80GB drives for that computer. - Peter On Saturday, December 10, 2005, at 10:57 PM, Philip J Robar wrote: > > On Dec 10, 2005, at 2:28 PM, Richard M.
