	We got in a shipment of hard-sectored disks for our Apples by
mistake. I attempted to use them, as I could also see no reason the Apple
couldn't use hard-sectored disks (you are of course right about the Apple
using soft sectoring). Well, the hard sectored disks formatted perfectly,
and *seemed* to work at first, but quickly began to get habitual write
errors. These were good, name-brand disks, by the way.
	I can't fault your logic - I still don't understand why the hard-
sectored disks didn't work. But I thought I'd better warn those who want
to try it to be cautious - don't be too quick to commit valuable files
to these disks.
