Reminds me of a 5.25" FH SCSI disk (1Gig I think) made by HP... the
drive would spin up, and then 'ding'. The ding noise sounded like it
had a little speaker and was saying 'I'm ready now'. But there
obviously wasn't a speaker on the hd.... I still don't know what
made that ping... it was fairly loud... it definately was a
conversation point... think I still have it somewhere too...
Also... one of my XT-1140MFM drives that I had in my second PC...
it used to make an annoying whine when the heads would rest in
the 'outer half' of the disk.... such that I finally wrote a
small assembly program compiled to a COM file that would call the
BIOS to move the heads to track 0.... I called it q1140.com...
when it irritated me... I'd type q1140... and all would be quiet...
