Common hard disk failures

Hard disk drives could fail in any of the following ways :

Electrical Failure
Firmware Failure
Mechanical Failure
Bad Platter Area
Logical Failure
Complex Failure Mode
A 2.5″ hard drive PCB Board
Electrical Failure

The PCB is the “middleman” of sorts, controlling, communicating and coordinating to read and write data between the hard disk and the computer. As such, if the PCB gets damaged due to power surges or power spikes, you lose access to your data. Frequently, the pre-amplifier circuit of read-write head may also be affected.

Symptoms
Drive is powered, but shows no sign of function
Disk knocking as the motor fails to spin
Clicking sound as the heads search or initialize
