If you can write a program to do the different combinations of track
seeking and the wonderful "drive is very angry with you" (disk read
error) sound, then I can sample them very cleanly for you (I have a
good setup for doing that sort of thing easily)

Or I can sample a few disks arbitrarily and splice up the different
audio events by best-guess.  Either way.
