Have you read about using Firewire Target mode to do the copying? That would require a Firewire card in your G3 but they are cheap, if you don't already have one. Just connect a Firewire cable to both computers, press "T" when you start up and your G3 will appear on your G4 desktop. I've only done it once but I think I got it right. "Target Mode" is in your manual and on Apple's website and other places. Ron/TN
