	 As far as I know, most of the Pro series 105 drives
have been immune from the "stiction" problem that has been killing the 40 and
80 Meg Quantums. I'm not sure why your drive is doing what it is, but it 
sounds to me like a part of normal operation. I've always noticed that my
Mac II and also the MacIIcx at work does this occasionally. I think it depends
on what programs you're running etc.. 
	What happens if you have the ROM fix installed on a Quantum is a random
exercising of the head arm that can last for several minutes and is quite
noticable. This exercise routine drastically degrades the performance fo the
drive when it is occurring.
