Ach te twoje mądrości. To nie chodzi o "nasze" testy, a o budowę dysków twardych i ich zasadę działania. Nie ma takiej opcji, żeby głowice po odcięciu zasilania nie wracały do strefy parkingowej. Szybko było by po dysku. Lepiej się doucz zamiast farmazony wypisywać.

All the hard drives are provided with the mechanism of an automatic parking at power supply turn off. Usually the auto parking is carried out by kinetic energy of magnetic disks rotation. At deenergization spindle motor is used as the generator, and the energy extracted from its windings is used for moving the magnetic heads to parking position before lowering of speed of rotation below critical level at which magnetic heads start to touch the disk surface. After heads reach the parking zone, the blocking of system of positioning by a magnetic latch (a small constant magnet) is performed, and smooth landing of heads to the magnetic disk surface is carried out. In modern storage devices the alternative method is applied - instead of allowing magnetic heads to fall to a surface, heads are completely removed from magnetic disks on a special parking platform. At power-up the disks are being spun to the necessary speed, then heads "fly down" from the platform on a surface of plates which turns at speed high enough to avoid the contact of the heads with magnetic plates.
