The user guide for my old Sawtooth said use master/slave jumper settings for internal hard drives. The user guide for my QuickSilver says use cable select. That's what I am using and it seems to be fine. But I still see references to master/slave on QuickSilvers and later G4s. What's best or does it matter at all? Thanks.
