Detecting Hard Disk Failure Before It Happens

Dealing with a crashed hard drive can be a heartbreaking experience. Unless you were making regular backups of your data, chances are you lost something in the process. Even if you have all your data backed up, you will still have to deal with the time-consuming process of replacing the drive, reinstalling software, restoring data, and more.

Sometimes a hard drive crash will take us by surprise and there is nothing you could have done to prevent it. I’ve seen hard drives die in brand new machines. However, there are often plenty of warning signs that your hard drive may be on its way out. In this article, I’ll discuss what you can do in order to catch a hard disk failure before it happens.

Mechanical failure is when the hard drive suffers from a physical problem that hinders its ability to function. It could be caused by the motors inside failing, or even from dropping the hard drive and causing some kind of physical damage. Excessive amounts of heat can also cause the internal components of a hard disk to wear down prematurely.

The main difference between file corruption and mechanical failure is that you can take measures to prevent and repair file corruption, but you usually can’t fix a mechanical failure.

Hard drives generally make a type of grinding noise as they work. Some drives are very noisy and some are very quiet, and it all differs from brand to brand. Because the hard drive has moving parts inside, such as the motors that spin the disc and move the read/write head, you will sometimes be able to listen to those motors and tell if there is a problem.

One definite sign that your hard drive is going to die is called the click of death. If you hear a steady click or ticking sound coming from the drive, then it’s about to fail. Another thing to listen for is an excessive amount of noise. If it sounds like the hard drive never seems to rest, it could indicate a problem. It could also mean you need to defragment.

Basically, any abnormal sounds coming from your hard drive need to be considered a warning sign that the drive may be mechanically failing. If you hear anything suspicious, you should run CHKDSK and defragment the drive.
