More to the point, why didn't you just install a 2.4.18 kernel and use the Adaptec-supplied driver and the RAID-1 capabilities built into the card's firmware? (Note, I'm not trying to disparage Jeff's work on libata here.) I have this setup and it works flawlessly with a pair of 160GB SATA drives. -Bob
