I have a question on the number of heads/sectors-per-track/cylinders
to use with this drive under NetBSD 1.0 (386 version if that matters).

Since this is a Zone Recording type drive, i.e. variable number of
sectors per track are the numbers in seagate's specs (at the end of
the mail) for the drive the ones to use for making an entry in
/etc/partition. More simply are 19 heads, 111 sectors per track, and
3992 cylinders going to work?

Already low-level formatted at the factory with twelve spare sectors
per cylinder (all twelve spare sectors are on one track) and two 
spare cylinders/unit.
