As I do some computer adjustments, I don't call this repairs, I see
people who "will try anything".
So a "deflated" looking gentelman appears holding a plastic bag with HD
in it.
A brand new 40Gb, which he "tried" to hot-swap, by his story it gave a
puff of smoke and went on strike.
OK, we found the proper tools to remove the special screws that hold the
printed circuit in place, carefully (I do this VERY rarely) lifted the
board and discovered a blown surface mounted IC. ( Of the 1cm/sq and
about 80 connecting points kind).
Being resourcefull we ordered another HD, exactly the same model so we
can swap the circuit and recover the treasures hidden on plates.
When it arrived, we swapped the electronics, NOT hot-swapped it to a
working box, the BIOS recognised it but the sounds coming from the
mechanics were of the kind you hear in horror movies.
