Indeed. I've used big pans of ice sat upon the drive before as a way of
keeping the temperature down long enough to get the data off - seems to work
well (just use something as a non-conductive barrier on the PCB side).
If that Seagate drive is the one I'm thinking of, they had a reputation for
running hot and slowly cooking themselves :-( I think I have one with a
narrow interface still, but it's overseas so unfortunately I'm not getting to
it any time soon.
If the problem is heads stuck to platters, then worst-case you could open the
drive up and try freeing them by turning the spindle manually - I've had good
results with that in the past. Do it in as clean an environment that you can
manage (and ditch the drive afterwards, obviously).
