Part 1: Possible Reasons Behind Unbootable Hard Drive

Hard drives are, without a doubt, the most important storage type among all varieties of permanent storage used in personal computers. They house all programs and programs that make the system works. in short, hard drives are the centre of the personal computer.

When an important entity like the hard drive then becomes unbootable, the situation that occurs means that it is unable to load the operating system on it. When you are unable to load or boot your system, then your files and data become unrecoverable.

The reasons behind unbootable hard drive are numerous. Some of these include:

1. Hardware failure

It has been over 50 years in the development of hard drives and we cannot say the hard drive is perfect. It is far from being perfect. One of the major reasons why a hard drive can become unbootable is a fault in one or more of its hardware components. The hard drive has a read/write head which works on the platter. These heads are not supposed to meet or touch, however, has it has often been found, these heads do meet. And when this happens, damage occurs and it renders the hard drive unbootable.

The controller board and even the platter can be corrupted due to various reasons. When any of these occurrences happen, you have on your hand, an unbootable hard drive.

2. Heat

Hard drives are susceptible to heat, but that is not good for their proper functioning. When a hard drive gets too hot, its platter will expand the real problem occurs when the temperature reduces – contraction. When this happens, micro-cracks that results from the distorted magnetic surface is what is discovered and this will lead to a comprise in the stored data.

3. Liquid damage

Most products in the market today are not designed to be water resistance or even any liquid at all. When a liquid is then spilt on a computer device, it can render it useless. Your hard drive, in this situation, can become unbootable. If the system is working when the liquid was spilt, the system can go off on its own accord and not come back on when the power button is pressed.

Liquid damage is a major reason why your hard drive can be unbootable.

4. Power surge

When the flow of electricity is interrupted, a power surge can occur. This can make the read/write heads of the hard drive to function improperly. What can also happen is the heads failing to get back to the parking zone – this is often caused by an insufficient amount of power. All of these can leave your hard drive unbootable.

Power surges can be caused by lightning or power line interference. Unfortunately, when this happens, there is little to what can be done to prevent it.

5. Human error

Reasons behind unbootable hard drive can also be caused by you or any other person using your system. Accidentally deleting of the operating system files can lead to failure of the system to boot. While human error might be unintentional, it is the most common reasons for hard drive failure.
