The whole impetus behind this was that I was trying to
read an old 360K
(might even be 320K or even 180K, I'm not sure) disk and while I could
read the directory, none of the files larger than say a cluster could be
read. I attributed this to the drive not being a "true" 360K drive.
There is no problem reading a true 40-cylinder disk on an 80 cylinder
drive (provided the software knows to double-step it). The problem comes
if you write to a 40 cylinder disk on an 80 cylinder drive and then try
to read it on a true 40 cylinder drive.
I remember writing a FAQ about this a couple of years back....
