The thing that CDC is refering you to is what they call Zone Bit Recording,
or ZBR.  This simply put means that there are zones on the drive that
have a different number of sectors per zone going from 54 sectors/track
to 32 sectors/track.  The different number of sectors is hidden from the
SCSI interface as the interface represents logical block addresses only.
I have used the CDC Wren V drives for quite some time under SCO and
have had no problems with them.
