What are the different ways of hard drive failure?

A hard drive may fail due to multiple reasons. Some of the common causes are:

- Head Crash: This is caused when the read / write head comes in contact with the platter. This can cause the area where it has come in contact to lose data.

- Bad Sectors: The platter in a hard drive is split into minute areas known as sectors. Sometime certain sectors might become faulty, this does not affect the entire drive.

- Stiction: Sometimes the head of the disk is not able to take off, it tends to stick to its position. This phenomenon is known as stiction.

- Circuit failure: The hard disk become inoperable if any of its circuitry malfunctions.

- Bearing and motor failure: After prolonged usage the hard disks motors or bearing tend to worn out hence not allowing normal disk performance.
