This kludge is unnecessary, of course, if you are using a dual speed
drive (such as some of the TEAC HD drives) with a dual speed controller
(the floppy controller on many Adaptec cards, such as the 1540B, can be
set up this way).

Then, since the drive is always running at the "right" speed for the
type of disk, there is no need to have different data rates.
