. . . and also, disks that were used on one system and then reused on a
different one.  The first side has a different format than the second
side, nine sectors per track with 8 used for a different file system than
the ninth, or a bogus MS-DOS directory left behind on track 0 and a CP/M
directory on track 2.

. . .  or calling 3.5" diskettes "hard-sector"

. . .  or calling 40 cylinder DSDD "Quad", and calling 80 cylinder DSDD
"SD"!    (Superbrain)
