Garner Products, a data elimination firm, has a machine that it claims can process 500 hard drives (the HDD kind) per day in a way that leaves a drive separated into those useful components. And the DiskMantler does this by shaking the thing to death (video).

The DiskMantler, using "shock, harmonics, and vibration," vibrates most drives into pieces in between 8–90 seconds, depending on how much separation you want. Welded helium drives take about two minutes. The basic science for how this works came from Gerhard Junker, the perfectly named German scientist who fully explored the power of vibrations, or "shear loading perpendicular to the fastener axis," to loosen screws and other fasteners.

As Garner's chief global development officer, Michael Harstrick, told E-Scrap News, the device came about when a client needed a way to extract circuit boards from drives fastened with proprietary screw heads. Prying or other destruction would have been too disruptive and potentially damaging. After testing different power levels and durations, Garner arrived at a harmonic vibration device that can take apart pretty much any drive, even those with more welding than screws. "They still come apart," Harstrick told E-Scrap News. "It just takes a little bit."
