Thanks. That's clear. But I had forgotten all about the 120GB drive that was on the secondary channel for the past year, which doesn't have a limiting jumper on it. Somehow it was always detected. I don't recall how I did it (I installed that drive for my friend). The 120GB drive is now installed on his new Win2000 machine, and I don't want to jeapordize the data on it by moving it back to this old machine just to test out what's going on here. I may change my mind if I can't figure this out. I at least have to verify that there is/isn't a limiting jumper. It's a Seagate 120GB, about a year old -- anyone know offhand? And is there any other way other than the jumper that will allow a drive to be detected on a machine that sees only up to 32GB? TIA.
