Computer hard drive is made up of several mechanical and electronic components. They work together to make the hard drive able to store data and access data from it. In some situations, you hear unusual sounds from the hard drive, which indicate that drive is failing. Hard drive failure is one of the most critical situations, which a computer user may face as it leads to serious data loss situations. In such cases, you need to opt for data recovery solutions to get your valuable data back.

The hard drive noises may occur due to a number of reasons, ranging from physical failure to disk platter errors. Three most common and frequently occurring reasons behind it are as follows:

• Read/write Head Crash: It is a type of physical damage to hard drive platters when head scratches platter surface. It results into grinding sound, which you hear while working on the hard drive. In such cases, first of all shut down your system and don't try to power it up again. Prolong power to hard drive would cause further damage. Head crash is the most frequent cause of hard drive physical failure and data loss.

• Mechanical Damage: This is the type of physical damage and the odd sounds might be cause by loose components, malfunctioning spindle, actuator arm damage and many alike. If you are able to access data from your hard drive, immediately create backup of all your valuable data. Hard drive is about to fail and may stop working anytime.

• Bad Sectors: Generally the hard drive bad sectors caused by physical damage to hard drive platters. The bad sectors of the hard drive can not be read from read/write head. When head attempts several time to read data from bad sector affected area of hard drive several times and it fails, you hear clicking noises. Perform disk surface scan to prevent operating system from being writing data on marked sectors.
