We're taliking 120 Gbyte drives here. Make a 1 Gbyte partition at the start of the drives. Install to the first. Clone using dd. Swap drives, you want to be _really_ certain this is going to work. Do the RAID setup on a second partition of each. Note that the second drive is a mirror. You cannot also use the space to store any kind of incremental backup. You _can_ store your incremental backups on another machine, on CD or DVD or tape, or even a third drive in the same machine. Note that ATA drive performance when you drive both drive on the same interface at the same time sucks. I still like two systems though;-) -- Cheers John. Please, no off-list mail.
