Mechanical Faults on Hard Disk Drives

One of the more common issues relating to the data recovery of modern hard disk drives is a failure of the internal moving parts of the device.  There are still moving parts in a modern hard disk drive.  These parts are the actuator arm of the read/write heads and the spindle motor that rotates the platters.  Both of these items will fail at some point, it is really a question of when, rather than if, they fail.  So how do you identify a mechanical issue in your hard drive?

The answer in short is: Very easily, at least in most cases.

Hard drives, for the main part, will begin to make distinctive noises when a mechanical issue is encountered. This page describes what to look out for when your hard disk has failed with the hope that it will aid you to determine your Problem.

Read / Write Head Assembly Faults generally cause a hard drive to click or to tick but can lead to other noises, or even the drive appearing to be completely dead. 

Seized Motor bearing faults often lead to a low pitched buzzing noise when seized completely, and a whirring or whining noise when they are in the process of failing
