OK, I'll give that a try later. Right now I'm trying to install Ubuntu 10.10 as RAID 1 on two new 2TB HDDs. The old boot drive is sitting in the machine (case still open), but it isn't attached to the SATA. Later I can just detach the two new HDDs, connect the old boot drive to SATA port #1 and try your advice. The thing is, I do want to switch to the two 2TB drives in a RAID1 (mirroring) arrangement. Even if the old boot drive were still booting, I'd have to do something to move everything to the new drives. I'm still not sure what that is, exactly, or how it would be different if the old drive were still booting. Mike
