The reason is that Apple drives (at least certain models) have 80 head phases;
with 2 phases per track, that means a 40-track capability. Since there is no
track 0 detection, if the head is indeed on track 0, then the disk drive has
to recalibrate by slamming the head against the stop 39 more times to MAKE
SURE the head will be on track 0 for bootup.

To insure my reception of any replies, please respond via e-mail. Thanks!
