For some reason, high density floppies (the kind that usually format to
1.2M on AT compatibles) *don't* work on 3B2s.  They seem to format fine,
but they fail verification, often in the very first track.  Regular DSDD
disks (which usually format to 360K on a PC clone) work better, though
you're asking them to perform above their specs.  Disks especially made
for 720K work best of all.

Someone want to explain to me the difference between double sided,
double density, 96 tracks per inch (3B2), and double sided, high
density, 96 tracks per inch (AT)?  Does the latter store more sectors
per track?
