-As the original poster of the query, I;d like to thank everyone who
-has suggested reasons for my squeak. However, I've realized that it
-is not a disk drive thing (not that I don't have a ST 251 on my
-system, the source of much discussion a few weeks ago), but
-something in the video system.

I wasn't gonna say anything, but...
I can hear the high-frequency squeal from some video devices, including
my CGA monitor and many color tv's.  The squeal gets less annoying as
my hearing deteriorates....

You can check whether your squeal is monitor or display card --- just
turn off the monitor and see if the squeal stops or not.

A friend had a laptop with an LCD screen that squealed.  The noise went
up and down with the screen "brightness".  She took it back to the
(Zenith) dealer, who said that all the screens on that model squealed to
some extent.  However, my friend's machine was excessively noisy, and
the screen was replaced under warranty with one that was *much*
quieter.
