@slayer great, nice to hear you got 10.6.6 running smoothly. did you try the tonymac nvidia driver update at all? i have my HDs in sata 0 and 1 - i forget what colors those are, but i think they are vertically stacked. do you know if i need any certain jmicron kexts to enable all those sata ports? i jacked my back up and i'm not looking forward to lifting my case up and changing the cables haha.
