well hard drives are safe from magnets now-a-days anyhow....I did the "feds at the door" experiment a number of times with an industrial electro-magnet that can pick up 12'x6'x2" sheets of steel all day without breaking a sweat. Flip it on, slap a HDD to it, let it sit for 5 minutes, plug it back in, and voila, nothing wrong with it at all....I've also done the opposite route, and slapped a HDD on a De-Mager with the same results...no lost data.....magnets and HDD's today are a myth.....unless you precision drill a hole and mount a vial of acid on a pull string, your data is relatively safe from anything other than mechanical failure...but I'm not paranoid or anything...lol...
