I'm curious, is the SCSI disk in question a removable?  In reading 
through the SCSI-2 documentation I see the Mode Sense command can extract 
parameters from three different sets, the "Current", "Saved", and 
"Default" values.  Mkfs always extracts the "Current" set, and I'm 
thinking that for removable media which hasn't had a "Saved" set written, 
these will be zero or undefined. If I'm correct, we should be extracting 
the "Default" set for removable media if the "Current" set returns zero 
or undefined values.  I'd like to check it out, but I don't have a Zip or 
SyQuest drive.  I haven't looked into the type of values being extracted 
my "newfs" running under NetBSD though, so I may be off base here.  Can 
anybody else shed some light on this for me?
