Didn't we go through this last week? The coercivity of the media is
different between DD and HD disks (not very different in the case of 3.5"
ones, but it's still different).

I would think that in the case of 3.5" disks, you could format an HD disk
as a DD one, but it will _not_ be reliable. It's the sort of thing you
might have to do if DD disks become unobtainable (and then I might
consider modifying the DD drive to increase the write current a bit), but
while you can still easily get the right media, please use it...
