Not until powered down, at which point it makes the noises I'd expect
(taking 2-3 times as long to spin down as the fan, for example).

Thought I was being clever, but Oh Well.

Both the head seek and the platter spin noises are consistent with
what I recall from before the failure, so I'll bet that chip is OK.
It's warm, but I can keep my finger on it for seconds at a time, with
no blisters arising.
Started looking for similar drives to mail-order for a controller board-swap.
Thanks to all responses so far!
Progress about to come to a screeching halt on the project, as I'm
about to hit the road again. Sigh.
