finger to keyboard and composed:

I had caught the other two drives before the part burned
up completely. No problem, when I connected them up the
fuse finished its burn and was easy to identify. Again
I clipped the fuse out, cleaned up the debris, and
both drives were seen.

It's not a fuse, it's a diode. A fuse goes open when it fails, whereas
the TVS diode goes short circuit. A fuse is in series with the supply,
whereas a TVS diode is in parallel with it, reverse biased, of course.
