Hmmm. So "wrong disk" is equated to "no disk".
Did they PLAN it that way to reject the other disks that were being
planned for, (I assume that they knew about the future diskette types
before we did), or did they just get lucky?
Yes. The "density" was software controlled. You could still format a
"720K" by using /T:80 /N:9, or /F:2, or later /F:720.
NOTE: XP has discontinued F:2 and F:720, but /T:80 /N:9 still works.
Different people place different values on their data.
...and now that AOHell sends out CD's, we will all have to BUY our
diskettes.

No, but
"DD" drives initially, for obvious reasons, did not have a switch.
True
DD drives probably still don't :-).
Incidentally, the Sony drive used in the HP9114 that started this
discussion does have a switch that lines up with the HD-hole. It's used
to detect that a disk has been inserted, and therefore, these drives
don't even recognise an HD disk (they think the drive is empty) And, I can
easily show you "HD" drives that do not have a switch! IBM did
not put a switch in their original "1.44" drives in PS/2's. Some users of
How did they work? Did they use the HD write current for all disks? Or
did they use the density select line from the controller, like the 5.25"
1.2M drives do? I would hope the latter. At no point
has the price differential been so extreme as to justify using
the wrong diskette on a regular basis. Admittedly, there can be
FWIW, the street
price in the UK at the moment is at least a factor of 2
(with the DD being double the price of the HD). This still has not
convinced me to risk my data :-)
