When Hard Drive Fails, How It Can Affects Your Computer

Hard Drive Repairs Crawley

Hard drive or HD or HDD is the computer’s main storage media device that permanently stores all data on the computer. It is where all your files and folders are physically located. It’s an inconvenience when your system crashes, when you have a faulty hard drive. It just means your data is destroyed unless you backed up, of course. But why do hard drives fail? Lets find out here.

  Hard drives form the basis of our computing. The use of computers comes down to manipulating data, and the hard drive is, of course, where we store all our data; family albums, music, work documents, email, the list goes on. Most of the components in your computer are electronic devices. They don’t fail with time like a mechanical device such as a car. But your hard drive is one of the few mechanical devices used in modern computing, and as such, it’s destined to die eventually. It’s important to learn to recognize the warning signs of an imminent hard drive failure, since you might not have the budget for an extensive back-up system, so you can rescue all that data before it’s lost—sometimes forever, not retrievable at any cost.

Logical Failures

Logical failures occur when the electronics of the hard drive failure or the software (firmware) has a problem. This kind of failure is usually the cheapest and easiest to have fixed. Unfortunately, it’s also an uncommon failure.

Media Failures

If the hard drive has been handled roughly, or the magnetic platters are scratched, have read/write errors or low-level formatting problems, this is a media failure. These are also relatively uncommon. Once the platters are scratched, the data should be considered scrapped.

Head Failures

A head failure occurs when the read/write head crashes into the platters (the head crash), has an “improper flying height” or the wiring between the logic board and the head is faulty—among other failures related to malfunction of the read/write head. This is a common failure. The head crash is particularly nasty.
