Many diskette manufacturers put QA info on cylinder
80, side 0,
including manufacturing date, which can be very
handy sometimes.
Neat - I didn't know that. I'll have to check for
that.
But I've got at least two drives in my collection
that will "hang up"
on cylinder 82--the head sticks and will not
retract--requiring
manual intervention. There are other drives where
the position hits
a stop after cylinder 81.
Interesting - I've never seen a drive do that. I
haven't had a problem with 82 cylinder disks, but I
can definitely see how some drives might not like it.
It's hardly in the spec. But then again, an 82
cylinder disk only requires it to step out to cylinder
81. I have had problems formatting 83 cylinder disks,
where the drive would be required to make it to
cylinder 82. Some drives do it fine, others don't.
Never had one get stuck though.
And the manufacturer doesn't QA the media that
far
anyway.
From what I've seen, they don't QA media at all
after
about 2001
