  I think that you are confusing DSHD and 96tpi
which are not necessarily
 the same thing.  Most DSDD disks will format to 96tpi (720k on 5.25"), 
 Odd... I've had a lot of problems doing that. In my experience, most 360K
 (DS 40 track) disks will not format to 80 tracks (and won't format on a
 Sirius, or a CBM8050, or...). 
Interesting.  I've *never* had *that* problem, except with disks that were
definitely defective (weren't reliable on any drive), although I had a few
really old ones that worked fine as SS but not DS.
