Most of the digital information in the whole world is stored on the desktop hard drives. When a mechanical shock happens, hard drives may experience damage caused by the read/write heads dropping down onto the moving platters. Normally these heads float on a thin layer of air over the spinning platters, but if a shock happens and the two do come in direct contact, the heads can literally become “glued” to the plates. When this does happen, the heads can only be “unglued” from the plates by a trained engineer using special equipment.
Also, regular desktop hard drive platters are not a subject of full media certification. The times when you could run low level format on your drive are gone. Modern manufacturing process accepts some percentage of bad sectors, which are placed in a so called “P-list” at manufacturing time and are skipped by the hard drive during regular operation without involving the file system software.
High-capacity hard drives use three or more magnetic disks, or platters. Because of this, the most common failure is a wedging of the drive's axle. The additional platters increase the load on the axle, and the resultant physical stress often leads to premature motor failures. With high-capacity hard drives a drop of only 4 inches can be enough to wedge the axle, which will first manifest itself through increasing hard drive noise and vibration. Some hard drive vendors’ designs make drives particularly vulnerable to such shocks and pressure. For example, when vendors Don't secure the hard drive axle with a separate screw to the drive cover then any pressure exerted on the housing or cover can actually shift the axle, resulting in it changing its angle, and then damaging the platters.
