Ah. I was just curious. I assume that means there's not a simple
poke I can enter to change the time DOS moves the head in an I/O

DOS wastes a lot of time, since in most cases, moving back a few
tracks would result in a valid track, unless the drive door is open,
no disk is inserted, or the disk is damaged or not formatted.

You can change the number of tracks that recalibrate seeks back, but
after it's done, DOS expects the drive head to be positioned at track 0,
so there isn't much room to decrease the count.
Perhaps this is an off-the-wall idea: greatly decrease the number of
tracks the recalibrate seek routine uses (say only 8 tracks). When an
I/O error occurs, and the head is out way past track 8 (e.g. track
29), multiple I/O errors would occur until the disk head was actually
on track zero, but the buzz would only happen after the fourth recal.
Would it be much slower this way?
