How Does Mechanical Hard Drive Work?
Today, almost every server and desktop computer has hard drives. The supercomputers even contain hundreds of hard drives to record data. They store digital information and even let computers remember functions when it’s turned off.
The two important parameters of a hard drive are:
Data rate– The number of bytes/second a drive delivers to the desktop.
Seek Time– The amount of time between when a CPU requests a file to the first byte of that file is sent to the CPU from the drive.
Furthermore, to understand how the hard drive works you have to get deep into its accessories. It will help you recover the sound of clicking hard drive.
It’s an aluminium box having controller electronics on both sides of the box. These electronics handle the read and write mechanism of the motor which spins the platters. There are vent holes to let out external and internal air pressure equalisers.
When the hard drive is operating the platters spin at 3,600 or 7,200 rpm.
The arm holds the read and writes heads helping the hubs to move from the edge of the hard drive. The arm has the ability to move from the hub to the edge (back and forth) 50 times per second.
Platters inside the hard drive store data in tracks and sectors. The sectors are pie-shaped wedges while the tracks are the concentric circles. Here’s the image showing what the tracks and sectors look like. The yellow circle is the track and the blue one is the sector. These sectors are grouped together into clusters either on the operating system or at the drive.
Two main processes are involved- high-level formatting and low-level formatting. The high-level formatting writes the file-storage functions that include tables for file allocations into the sectors. Whereas, the low-level instructions write the functions on both the tracks and on the sectors.

- Your hard drive is having connection issues and is making a faint clicking sound
- Hard drive clicking excessively with loud noise
- The operating system fails to detect your hard drive
Possible Explanations For A Clicking Hard Drive
When a fault appears in the hard drive’s read/write actuator, the drive starts to make clicking noises indicating the signs of failure. When the hard drive is performing well, its actuator runs smoothly. However, if its motions become unexpected and erratic, the hard drive controller tries to reset its position by bumping back to the former position repeatedly, and this causes noise.
In the beginning, it’s hard to note the clicking sound although there is a major degradation going on inside your hard drive. Here are a variety of ways that can result in clicking the hard drive.
- The inefficient power supply is a major issue
- The use of incompatible cables leads to troublesome connections
- Issues with a hard drive that involves damaged service area, broken PCB, or misplaced dish head.
- Physical harm like extreme temperature or fire

You need to check if the cable is broken or has corrosion on it. Replace it with a new one before turning on your desktop. Lastly, if your USB cable version is 2.0 or 3.0 you need to make sure that this cable is not attached to the USB 3.0 hard drive as it will not work properly.
Whereas, if your drive is internal it’s best to take it out from your desktop and use it as an external drive. You can use drive enclosures to connect it properly.
Step #5- Cool The Hard Drive
