Well now, that's an interesting twist. They're definitely soft-sectored.
I was under the assumption that the physical media was different between
the types of disks. So the DSDD are the same stuff, just a little higher
quality oxide to support more and closer tracks?
I'll have to try to re-format one (tomorrow maybe), and see what happens.
...and yes, some did ship with dual 5.25" drives also. Thanks for the
info Chuck. :-)

Well, that blows that idea. I don't HAVE any
SSSD disks, just DSDD.
Back to the drawing board I guess.
Most 8" disks (assuming that the aperture in the jacket is in a position
that matches the index sensor on your drive) will work just fine in
either density or side-edness. There is no difference in the media coating.
The one thing that you do have to watch out for is getting a batch of
hard-sectored (33 holes punched round the cookie) when what you want is
soft-sectored (1 hole).

P.S. Doesn't the 820-II also work with 5.25" 48 tpi (360K) drives?
