ok well that whole electro magenet thing is bullshit. If the RIAA was really realy really bent on trying to **** you over, they will look over every square inch of your hard drive with an electron microscope and read it out sequence by squence, but they would loose MUCH more money than they would gain, since it would cost them about 10-50 thousand dollars (depending on the size, make, blah blah blah of your hard drive, and how many hard drives you had) than they would have to go through a whole court battle which would cost them 10-20 thousand, all in all they lose unless they sue you for some crazy amount like 100,000 - 150,000, and taht would never get through. I am gonna get a ****in external HD soon, I cant wait, because i ****in hate the RIAA!!! stupid mother ****s take our freedom.
