As I've said before, with a 360 KB floppy drive costing only $100, it makes no
sense to fool around, assuming that your work and your time have some value.

Perhaps the reason that people have been lucky is that the source and target
machines are at approximately the same temperature and humidity.  Floppy disks
are made from a poly-mumble-mumble film substrate that is notoriously non-
uniform in expansion/contraction according to temp. and humidity.

My own experience is that a Shugart (Panasonic) SA 455 has no trouble reading
disks written on the 1.2 MB drive, but the Tandon in my XT at work just flat-
out can't do it.  Works fine with all disks from 360 KB drives.
