	Way back when 2.88 was first invented, I had a 2.88 drive in my
desktop machine and a special floppy controller to make it work.

	What a disappointment.

	I currently have formatted one HD 1.44 disk as a 2.88 with my
ThinkPad, and use it to hold lots of DOS 6.1 stuff on it (for the purpose
of screwing around from a booted floppy--but for safety reasons, it is
definitely *not* the only one I have as a boot floppy!).  You're right--it
works.

	But I wouldn't rely on it.  Just like the people who used to punch
holes in 720K disks and format them as 1.44's.  Big mistake.  The bottom
line is that they aren't built to the same tolerances.  The magnetic media
is not as dense, and therefore not as safe.  Sure, you can format it for a
higher density, but the liklihood of failure increases manyfold.

	If you plan to use 2.88 format with any regularity, keep those 2.88
ED disks you bought.  If you do not, one day when you least expect it, one
of those 1.44 disks you formatted to 2.88 will fail on you and you'll be
quite unhappy.  Isn't the extra 1 or 2 bucks worth it to keep that from
happening at some critical juncture?
