   That sure sounds like a physical difference to me.  And also, as I
understand it, it's actually the other way round.  A 1.2M disk actually
uses a weaker magnetic field, which makes 360K disks written in a 1.2M
drive unreadable in many 360K drives.

   If the problem was that 360K drive heads didn't generate strong enough
magnetic fields, then I should be able to format 1.2M floppies at 360K in
my 1.2M drive.  Well, it doesn't work any better in that drive than it
does in my 360K drive.
