Duncan,
   Just a quick follow-up. I tested the WD Green drives for the last
36 hours in Spinrite and found no problems. I think the drives are OK.

   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
