Well it sounds dead. However, since you are resorting to extreme measures, you could try freezing it (google "freezer stiction"), after double-bagging the drive so as to avoid moisture penetration so far as possible. Ideally, if you live somewhere northern where it is winter, pick a really cold, clear day with Arctic air (-15ºC or colder), place the drive outside for an hour or two, and then try spinning it up. Frigid Arctic air masses are dry, much drier than a household freezer. Then, if possible, bring the machine outside and try starting up there so as to avoid condensation issues for the 30 mins or so needed in order to try to recover your files.

But the odds are that the drive is dead.
