Like most Computer Hardware; Computer hard disk drives eventually break down with normal wear and tear — more so if subjected to adverse conditions like poor overclocking, power surges and extreme weather. Somewhere down the road, you will have to entertain a computer hard drive upgrade to keep your system stable and safeguard your saved data.
When computer hard drives fail or crash, the problem can be classified either as a logical hard failure or as a mechanical hard drive failure.
* Logical Hard Drive Failure
In a logical hard drive failure, the computer hard drive is not broken. You still have a hard drive with a sound architecture, but the drive is not able to properly read and sort data.
Logical hard drive failures can stem from human errors like accidental file movement. If you accidentally delete, move or overwrite important system files, your hard drive can crash.
Logical hard drive failures can also be due to corrupted files such as in instances when your computer is attacked by a virus or other malware.
* Mechanical Hard Drive Failure
When you are dealing with a computer hard drive that has some broken parts such as a chipped arm or a scratched platter, then you have a mechanical hard drive failure. Broken hard drives usually give off a clicking noise when operating. If you hear a clicking sound when you turn on a laptop that has just suffered from a nasty fall, chances are that you have broken the integrity of your hard disk drive.
Unless they have been overwritten by newer data, data lost through a computer hard drive failure can be recovered. You can recover lost hard drive data on your own if you have a minor logical hard drive failure. When it comes to hard drives that no longer power up and physically broken drives, however, you need to seek the help of a professional computer hard drive recovery service.
