swapping the board is usually as easy as installing
memory. Usually. Four screws on each corner...
sometimes more. Board lifts off to find a pressure
clamp on the ribbon cable. Swap. retrieve data.. Swap
back and throw away drive unless you can order a new
board from drive manufacturer. Never had any luck with
that though. If you are in the area and want to drop
by. Bring the drives and we'll sort it out if
possible. Contact me off-list for directions. I
forgot to include, with the freezer trick you will
need something to absord any condensation. Being
florida and all, there is always condensation.. a
couple paper towels should do.. wrapped around the
drive in the freezer bag. Credit for this goes to any
excellent tech at the Florida School for the Deaf and
the Blind... A mentor and a really nice guy, Don
Hollingsworth.
BTW.. of course you always need to watch out for ESD.
