That wasn't the problem. I had formatted all the drives as Linux Raid auto
but when I replaced the drive it ws formated as linux. Consequently the
drive would not boot into the raid. It has taken me two week to figure this
out...my raid is now perfect, I have five 160 GB drives, three for data, one
parity and one spare giving a 450 GB raid partition. Additionally there is
one 80 GB OS disk and a 300 GB music disk. It's pretty heavy!
