3.5 inch drives are (by standard convention) only spec-ced to run up to 3ms
step rate.  Also, they are only specced to run up to 80 tracks.  Most drives
will manage 82, if you're lucky; and maybe half of them will manage 2ms
steptimes.  If you go beyond the specifications, you run the danger of
garbaging the disk drive.  (Which is YA reason why track 81/82 copy
protection is a REAL BAD idea.)  I'd say that 83 track/2ms step was really
pushing your luck.

Whether trashing a drive could then infect the rest of the machine would
then depend, I suppose, mostly on what the drive does when it goes.
