Did you check all of your jumpers? The drive at the end of the chain should be set to "Master" and the one in the middle of the chain should be set to "slave". Using "cable select" (usually the default) with drives from different manufacturers may cause problems? (although it shouldn't) I've never used Western Digital specifically, but I've never had a problem with mixed manufacturer drives in the same computer, or even on the same IDE bus, and I always manually set the drives to "Master" or "Slave" mode, depending on where it's installed on the ATA/IDE chain. - Mark On Friday, January 31, 2003, at 10:47 PM, animal wrote: > After adding a 120 GB IBM (ATA) to a G4 400 Sawtooth AGP, I then > replaced the tiny 10G stock Maxtor with a 120GB 8m cache western > digital.
