Hard disk drives – why do they fail and what can you do about it?

data loss
If a hard disk fails, most of us have a similar kind of panicked reaction: I have lost my data forever!! How am I ever going to get all this data back ?

The fact is hard disk failure as well as the resulting data loss is not easy to repair or recover on your own. Even though recovering data on your own is feasible in some instances (such as simply recovering deleted files) you often risk doing more harm than good and may well mess up the likelihood of a successful recovery if you don’t understand exactly what you are doing.

Here’s a guide to why hard disks fail some signs of hard disk failure and what can you do to avoid it?

Why do hard disks fail?

Hard disk failure can mainly be attributed to physical and or logical damage.

Physical failure : Physical damage to the hard disk might occur due to external forces like shock(bumping, dropping, jostling), water, heat, sudden electrical or power failure or a power surge factory faults and mechanical failure . While most components of a computer are electrical the hard disk is one of the few mechanical parts as in it has moving parts. Therefore it will unavoidably fail at some point. A physical failure occurs when the read-write head or any other components become faulty due to normal wear and tear.

Logical failure: Logical damage to the hard drive might occur as a result of corruption in the file system which can be caused by:
– Viruses, malware, or corrupted files
– Human error in the event you occidentally delete an important registry entry or if you format the drive improperly.
Usually this sort of damage is recoverable simply because no physical damage has been done to the drive.

Signs of hard disk failure

  • Clicking or grinding noises while running;
  • Files mysteriously disappear usually more than once;
  • Locking up through the boot process – hard disk problems are indicated if this happens frequently;
  • The computer often freezes and when it does you are left without mouse or keyboard input and have to do a hard reset;
  • Standard file processes like saving and opening slow down interminably even for small files;
  • Increase in the number of bad sectors noted when running chkdsk;
  • You can’t speed up computer performance even by applying optimization tricks;
  • You discover that your computer is unusually hot.

What can you do?

You can prevent most causes of hard drive failure with common sense and a little planning. Additionally recognizing the warning signs of failure can easily help minimize the potential for data loss.

Inadequate ventilation can lead to overheating and eventually cause hard disk damage. Make sure that your computer’s fan (generally situated on the base or rear of the machine) isn’t obstructed so that it can provide adequate ventilation; your computer should never be too hot to touch. Water and shock damage can be hard to avoid this usually happens fairly quickly and unexpectedly. Taking good care of your computer is the best way to combat these kinds of potential risks.

When you begin to experience signs and symptoms such as disappearing data, disk errors as well and perhaps a sluggish system the best thing to try and do is back up your data if you haven’t done so already. If you can’t access your data professional help like a hard disk recovery service is recommended.
