Re: Clicking GS

[Blake Patterson <blake@blakespot.com>]

	I removed my 5.25" drive from the GS as I've little need for it right
now.  With the speakers turned up (and not even WAY up) I definitely
hear the clicking.  I've just got an Apple 3.5" drive hooked to it (the
"GS" 800K drive, not a UniDisk or some such other drive).
