The answer may surprise you. Something strong enough to corrupt the data would likely destroy the hard drive, along with everything else in the room, before it would have a chance to corrupt the data. This allows active tags to produce stronger RF signals, which can travel over a greater distance to the transceiver. But already a third of this field strength is enough to partially delete magnetic stripes so that they can't be properly read anymore. A prolonged exposure of a neodymium magnet of strong magnetic field can erase the data permanently from the stripe and can make the card unreadable. We have the pictures to prove it. Inside many computer hard drives, there is a small neodymium magnet. The Internet Patrol In the case of MiniDV tapes, smaller cube or disc magnets you can clutch between the tips of two fingers should be all you need.
