Hard drives only at first glance seem fragile and defenseless, but at the very "stuffing" is a solid structure, which is quite difficult to bring to a completely hopeless state. There is, for example, a case in which the drive, which has consistently been under the wheels of a car, is in the toilet, and then thrown out of a window on the seventh floor, was then disassembled, dried, and it was possible to calculate the data. Thus, even throwing out at first glance a completely failed hard disk, one cannot be completely sure that information from its plates cannot be read using specialized equipment.

"Therapeutic" measures in the form of applying end-to-end encryption of data on the hard disk during operation and repeated overwriting by zeros of the content of the device that has served its own is not always acceptable. The latter, moreover, takes a lot of time, and it may simply be impossible if the drive stopped working normally. Powerful magnets also do not guarantee complete erasure of all information. If one does not consider various exotic methods of “killing” devices, such as dissolving them in acid, or melting in a blast furnace (tea, not the Terminator, though), banal mechanical destruction remains at the disposal.
To securely crush hard disks on an industrial scale, EDR Solutions offers a special device - Hard Disk Crusher. The terrible name does not quite correspond to reality - in fact, the drives do not break down into separate parts, but are drilled in the spindle area. It is claimed that due to this, the surface of the disks warps, and becomes completely unsuitable for reading data from them. The performance of this “hard drive shredder” is 60 drives per hour, the price is 11.5 thousand dollars.
