Well... having had to deal with this situation a number of times, I'd add
one more comment. From the time you press 'load', you have about 15-20
seconds before the heads load.

When I'm dealing with unknown packs with the 'shockwatch' tripped, (after a
close visual inspection) I keep a hand lightly on the drive while it is
spinning up to help detect unusual vibrations. (you get used to the normal
'feel' after a while) A badly pranged pack will often give itself away in
time to abort the load (and save the heads).

YMMV! B^}
