The way a 1.2M drive works to squeeze that data on, is to change the disk
rotation speed and to double the number of tracks to 80.  If you pay attention,
you should notice that a 1.2M drive will take slightly longer to begin reading
a disk when you have changed formats.    This however, is not how a HD 3.5"
drive works.  (1.44M)  A standard 720K 3.5" drive has 80 tracks with 9 sectors
per track, while the 1.44M still has 80 tracks, but has 18 sectors per track.
