[comp.sys.atari.st] hard disk parking

FORTNEY@FNALB.BITNET (01/23/88)

   If PARK tries to reopen the desktop, what then is the difference between
PARK and SHIP that is supplied by Atari?  On my SH204 I found that SHIP
seemed to struggle trying to reopen the desktop, but PARK seems to lock
everything up with no apparent struggle.
   Am I really doing something wrong?  Why doesn't PARK or some similar
program just hang in an infinite loop until I turn the machine off?  Why
doesn't the head lock mechanism disable the head drive motor so that the
software can try to reopen the desktop all it wants without harm to the
hardware?
