I then took the two 500GB Raid Enterprise drives above and made a new RAID1 on which I did a quick Gentoo install. This uses the same SATA controller, same cables and same drivers as I was using earlier with the Green drives. While doing the install I saw no problems or delays on them. Now I've got a new RAID1 install but cannot get it to boot as grub doesn't seem to automatically assemble the RAID1 device. I'm moderately confident that once I figure out how to get grub to understand / is on RAID1 then I may be in good shape. Thanks for your help, Cheers, Mark
