Ok here is what I found out. The same hard drive that was killing my cube made a G4 800 Tower do the same thing. Reformated the drive and installed Leopard from a 1 gig g4 laptop using the drive from the cube as a firewire device ( used a Wiebetech drive dock, everybody should have one ) The drive booted and ran fine on the G4 tower ( 800) then moved it back to my cube and it works without any problems I can tell so far. I can not tell if it runs any faster or slower on the cube. I have a Radeon 9000 pro in the cube. ( 64 meg ) I will keep you posted. Gary H.
