The OP bought his QS new in May 2002. And at this very moment I have working here 2 QS's 800 2002. One produced in week 06 the other in week 12. The "older" one has a 320 GB HD + a 80 GB HD, both on the normal ATA-bus. The "newer" has 500 + 320 GB HD's on the normal ATA-bus and a 80 GB HD as slave of the superdrive. Both QS's run 10.4.10 and 10.3.9. No other SW needed, just plug in the big drives and go. Jo Hissel
