OS X shutdown

[Keith Feltham]

When I shutdown the B/W G3 from OS X it makes an unpleasant popping 
sound, followed by a whine that lasts for about four seconds. This is 
exactly what happens when Western Power treats me to one of their 
splendid and frequent power cuts. It is as if (wild guess here) OS X 
cuts the power before the HD heads are parked. Doesn't happen from 
System 9.

Anyone else get this?
