Washing machine? Are you serious?
Here's the real scoop on the Hard Drive
TRY THE FREEZER THING... if it doesn't work... here's the possible scenarios:
1. If you're Hard Drive is getting power, go to the yellow pages and look up data recovery. You may still be able to recover the data. There's a guy where I live who can recover data for about 500 bux (and that's the cheapest I've found).
If you're not getting power to the hard drive... the hard drive would have to be sent to a cleaning room where they take it apart and literally clean the platters and replace the mechanics inside (dummy terms) and see what data they can get off of it. And the cheapest I've found for doing that is about 1300 bux.
There are many other issues / solutions, but this is pretty much the just of it. And if you didn't have valuable data... don't worry about it, get a new one and be sure to back up your data moving forward.
AS for the Keyboard thing... I've never done it, and wouldn't suggest it. =O)
