PARK_HD.ACC by Dick Lee

     PARK_HD.ACC is my first attempt at programming the hard disk 
  
controller  (HDC) in Pascal.   The program was written  with  OSS 
  
Personal  Pascal.   I  guess I should mention  that  portions  of 
  
PARK_HD.ACC,  mainly the library routines, are copyrighted by OSS 
  
and CCD.   This program has been placed into the public domain as 
  
FREEWARE.


     I wrote this program as a result of being tired of searching 
  
for  the  head parking program (that came with  the  hard  disk), 
  
closing  any  windows  displaying the directory of  a  hard  disk 
  
partition,  and  then  running the parking program every  time  I 
  
turned off my hard disk.
  

     This  accessory  will  park your hard disk's  head  in  it's 
  
shipping position.  As with other parking programs, once you have 
  
parked the head,  you SHOULD NOT access any partition of the hard 
  
disk...  you'll hear weird noises and see some strange garbage on 
  
your window.   After PARK_HD.ACC has been selected, the head will 
  
be parked,  and a dialog box will appear telling you so.  The LED 
  
on  the  hard disk WILL STAY LIT (at least on  my  SH204),  as  a 
  
reminder that the hard disk head has been parked.   DON'T  WORRY, 
  
your hard disk isn't doing anything.  You can now turn your  hard 
  
disk  off.   You should only need to execute this accessory  once 
  
per session.  If you forgot something and wish to access the hard 
  
disk again, you should first turn off the hard disk and then turn 
  
it back on again; this will move the head back out.
  

     I  have only tested this program using one SH204 hard  disk;  
  
however,  it should work with multiple hard disks.   If you  have 
  
any questions or any suggestions,  please send me a  message;  my 
  
Compuserve PPN is [72717,1603].
