Park heads when moving Kaypro 10? - test-drb@ccmp.vtda.org

10 Oct 2002

Thanks, Bob.  I've been using this system off and on for a couple of years,
and it never occurred to me that I had to park the heads before each
power-down.  Apparently there hasn't been any damage as a result, but I'll
start doing it . . .

 I seem to remember that self-parking heads generally were not available on
...
  the 10MB drives of Kaypro 10 vintage, so I did a
little Googling and came up
...
  with the following

(http://www.atarimagazines.com/creative/v9n12/8_The_Kaypro_10_more_than_.php

...
  )  from CREATIVE COMPUTING VOL. 9, NO. 12 / DECEMBER
1983:

 "A very important command is included in the Kaypro 10 system software.
 SAFETY moves the read/write heads on the hard disk to the safe landing zone
...
  on the disk. This must be done before turning the
power off or the surface
...
  of the hard disk may be damaged. The SAFETY command is
invoked from the
 command mode in CP/M."

not to damage the hard drive?  
 IIRC, it is built into the operating system and when the HD LED goes
 out, the heads have been parked.
