>From what I understood, both SATA and SCSI drives can be modified
using sd.conf, but I don't have any drives I can test at the moment,
so either of us could be wrong ;-).

However, there is a sample listing of drives that can be entered into
sd.conf [2], and many (all?) of them are SATA, so that is where I
presumed it would work with SATA. Let me know if it doesn't, as I will
may to work with such drives in the near future.
