Yea, I had assumed that he would through the pack away. The drive is definitely
salvageable. Just make sure the heads are *clean*. That's why I talked about
re-alignment. The easiest way to make sure that the heads are clean is to remove them
from the drive. Allows you to make a good inspection (under magnification) that
you've cleaned them up properly and there aren't any remaining bits of the old
pack stuck to them.
As far as 12 sector packs, I've literally hundreds of them. So I know they're not
that hard to find. :-)

If I am in real luck the headcrash may be before
track 0. So the
disk may be usable.
Throw it away. It is not worth messing with a platter that has visble damage.
The head will extend almost all the way back to the edge of the platter at
track 0. There's no way it's going to fly if there is any physical damage
on the platter. I've dealt with literally hundreds of 2315 style packs.
12 sector packs are not THAT difficult to find.
Even one tar-looking smudge can crash the heads again.
If there are no scratches on the ceramic after you clean them, the heads will
probably be OK. 2.5 mb heads are pretty tough. The heads and disk surfaces
HAVE to be absolutely clean, through. No smudges, no scratches. There should
be no funny little noises as the heads move across the surface.
