Head Crash

the term Head Crash designates the loss of a non removable disk, with which she is mechanically damaged and data to be lost.

This damage is caused by the read-write head of the non removable disk, if this affects the surface of the storage medium. Normally is due to the Bernoulli law of the dynamic liftbetween the read-write head and the fast rotating disk surface a narrow air cushion.

As reasons for Head Crashs wear, wrong installation of the non removable disk, strong variations in temperature and general vibrations is considered (increased with mobile devices, z arise. B. with Microdrives in digital cameras or with laptops). In someMacs becomes therefore a “Sudden Motion” - sensor blocks, which takes the read-write head of the non removable disk with strong movement and thus overruns prevented.
