Hard Drive Failures: Common Causes

It has often been observed that all hard drives run past the three-year mark, but it also becomes imperative that you can predict the failures, to prevent data loss. There two types of failures defined, logical and mechanical. Below are a few causes for hard disk failure.

  1. Heat

This is the most common reason for hard drive failure. Overheated hardware causes the hard drive to fail. Inadequate ventilation and cooling around as well in your computer hardware can cause severe damage to the equipment. Overworked hardware with little or no downtime and smoke or fire damage can wreak havoc on a system.

 

  1. Physical damage

Bumping, jarring or dropping your computer/ hard drive may lead to some physical damage. If the hard disk is in use at the time of the impact, the read/write head might get displaced or damaged. It might also touch the disk causing damage to a magnetic surface. This might wipe out a few sectors of your hard drive. Even if your computer is turned off, there is still a chance that the hard drive may get damaged.

 

  1. Power voltage surges

Power surges can be induced in the system due to lightning strikes, interference with the power lines, short- circuit, power outage, or any other event that might cause the flow of energy to be interrupted and then restart. Power surges can cause the read/ write head to act up. It might also cause the computer to crash in some instances.

 

  1. Water damage

Moisture is proven to be deadly for any electronic or electrical item. Likewise, condensation caused by flooding or even spilling a liquid onto your hard drive is assuredly bad news. The casing of the hard drive is not specially designed to protect it against water penetration. It might directly affect your hard drive or might cause indirect impact, by creating a power surge. It might also cause the other components of your electronic system to malfunction which in turn cause damage to your hard disk.

 

  1. Corrupted files

Although corrupted files rarely damage the hard disk, we must not ignore this. Improperly closing a program, turning off your computer before closing all files and installing new software might cause files to become corrupt. We must, as and when we can, try to avoid such circumstances that might cause the hard disk to fail. Power failures and accidental shutdowns, although cannot be controlled, can cause serious damage to your program files.

 

  1. Human error

Sometimes the functions of the hard drive can be impaired by accidental human tampering of system files. Improper installation and removal of files from your computer can cause the hard disk to malfunction.

 

  1. Virus

Malware can also cause your hard drive to fail or malfunction. There are thousands of viruses and could attack your system in many ways. It can enter your system from the web or an infected pen drive or external HDD. These can either crash your whole system or can corrupt a few sectors of the hard drive.

There are effective ways to troubleshoot faulty hard drives and recover lost data from damaged disks, but first, you are going to need to find a data recovery service that works best for you.
