I have just acquired a MicroVAX 2000 which I found to

try booting the machine from the disk you hear a whine, when the whine stops
you can hear the heads move, then when the heads stop moving you hear the
whine again. Is this a terminally sick disk?
Thanks

Years ago, I ran an XT-2190 and an XT-1140 in a PC.
The 2190 did not have a whine... but the 1140 did... but I discovered
that it
only happened in a certain track range.... so I wrote a program that call a
DOS interrupt to seek the heads to a quiet track... compiled it and
called it
q1140.com. If the whine bothered me (and it happened to be whining), I
could
type q1140 at the DOS prompt and have the noise go away.
The drive worked flawlessly until it was retired.....
Never did know what the whine was.
