I recently downloaded TIMEPARK from simtel20 and it seems to work on my
PS/2 30-286 as described.

But one question hunts me: does TIMEPARK hurt the disk more than it 
tries to save? I suppose TIMEPARK powers off a hard disk before parking
its head. However, the power surge during power-on and off can be 
hazardous to a disk module. And the unstability of the head during 
those periods would make the hard disk more vulnerable to scatching.

Was there any study on this subject? Any information will be appreciated.
