Hard disk failure is the most difficult circumstance a
computer user can ever confront. This may bring about
data loss forever. Being an imperative part of computer,
hard disk failure can bring about extreme issues. You
can’t use a computer system if it doesn’t have a hard disk.
Indeed, even an invalid or corrupt hard disk can bring
about inaccessibility. Before going further from here, we
should first discuss hard disk and its significance.

Hard Disk Drive (HDD): Hard plate is essentially a storage device that can store a very
large amount of data and information, and give you quick access to them. It is otherwise called
the principle storage media device of a computer system. All your data which are stored in the
hard drive stay in it regardless of the fact that the system is turned off.
Importance of Hard Disk
 The hard drive allows your computer system to start. Without a hard drive, a computer
system cannot be booted up.
 Because of the hard drive, all your data and information are saved on your computer.
 All the functions and actions of your computer depend on its hard disk. Without a hard
disk, your computer system cannot be worked or functioned at all.
Now let’s discuss about crash or damage in a hard disk that makes it unable to be opened. Once
in a while people get mistook for operating system crash and hard disk crash. Both are not same
at all. There’s a contrast between them. Operating system crash happens because of logical
failure whether you’re using Windows, Mac or Linux operating system. On the other hand, hard
disk crash happens because of physical failure. In both these circumstances, your information
can’t be accessed but available there in the hard disk.

Determine Hard Disk Failure
To begin with you have to decide the factor of hard disk failure, i.e. logical failure or physical
failure, which causes crash in your computer machine. At whatever point a system gets crashed
down, it basically gets to be not able boot to the operating system. Error messages can help you
know the cause behind the crash, i.e. either logical or physical. As physical failure causes crash
in system hard disk, you have to think about it. On the off chance that your computer machine
doesn’t boot and you get a few hints of clicking, grinding or whirring noise, this implies the
accident in brought about because of the physical failure. Until unless the genuine cause is
resolved, neither boot your computer system nor reload the operating system.
Reasons for Hard Disk Failure
There are several reasons which may cause hard disk failure, ranging from manufacturer’s fault
to human errors.
Manufacturer’s Fault
Check for the symptoms given below:
 Your hard disk cannot be detected or recognized by the computer system anyhow.
 Your computer system fails to boot or it hangs while the booting process is running.
Solution: If your hard disk gets crashed down due to manufacturer’s fault, you must contact the
manufacturer or the person from whom you purchased the hard disk. You may also need to
contact the customer care center for hard disk replacement. You faulty hard disk will be replaced
with a new one and make sure that the hard disk is properly checked or examined before getting
delivered to you. Though you will get a new hard disk, but you will lose all your data which
were stored in the faulty hard disk. The hard disk manufacturer will not be liable to recover your
data from the faulty hard disk.
You purchase a brand new hard disk from a well-known hard disk
manufacturer. After a few days of purchasing, your hard disk stops
working. You get a crash in your hard disk. It sounds unusual, but this
can happen if there is any manufacturer’s fault in it. Usually what
happens, some faulty hard disks are delivered to the customers without
proper testing or examining.

Overheating
Check for the symptoms given below:
 Your CPU fans are moving very slowly or not moving at all.
 You find some clicking sounds and other unexpected noises are arising from your system
while booting.
Solution: If overheating is the cause behind your hard disk crash, you need to check the fans in
your cabinet. They must be working in a good condition. Faulty CPU fans cause overheating, so
avoid them. Do not forget to give proper maintenance to your computer system in a regular
manner. Always use a good quality of cabinet box that contains enough fans for proper cooling
of your computer system. Using SMART (Self-monitoring, analysis and reporting technology)
tools are highly recommended.
Unexpected Power Failure
Check for the symptoms given below:
 Your system BIOS (Basic Input Output System) fails to detect your system hard disk.
 Your system hard disk becomes unable to spin.
Solution: Make sure there is no interruption between your computer system and main power
supply. Check whether your computer machine is getting the required power supply or not.
Always use a UPS device with your computer system that provides power backup to your system
in the event of sudden power failure.
Unexpected power failure can cause minor or sometimes serious
damage to your system hard disk, and result in hard disk failure.
Sometimes low or high power supply can cause your system be
turned off in an unexpected manner. This happens if you are not
using a UPS or using a poor quality UPS device. Poor quality UPS
may not be able to provide the required power supply to the
computer system.
Overheating in your hard disk is one of the most common reasons
behind hard disk failure. The situation of hard disk crash due to
overheating occurs in a frequent manner. Improper maintenance of
your system, poor quality of cabinet box, faulty CPU fans, etc. can
cause overheating in your system hard disk. Sometimes high power
supply can also cause overheating in your system and can affect your
hard disk.

Mechanical Failure
Check for the symptoms given below:
 Your hard disk drive starts making click sounds.
 Files and folders in your computer system cannot be viewed or become invisible.
Solution: To avoid mechanical failure from hard disk, make sure you update your computer
system in a regular manner. Use an Antivirus program to scan your computer system for viruses
and do not forget to update it time by time. Never let your hard disk be old enough, i.e. replace
your system hard disk after 3-4 years even if the hard disk is in good condition.
Corrupted/Invalid Data
Check for the symptoms given below:
 Your files and folders, which are saved on your computer, cannot be accessed.
 Your operating system fails to boot.
Solution: Never ever turn off your PC in an abnormal manner. Always use the specified way to
shut down the computer system. Do not make haste to closing the running application or
programs. Give the required time to programs to get properly cancelled. Avoid installing the
applications which are downloaded from untrustworthy source.
Mechanical failure in your hard disk drive usually occurs due to some
internal causes which include bad sectors in hard disk, spindle motor
fails to perform rotation, power supply issues, and many more. An old
hard disk may cause many critical issues and problems, or if you have
formatted the hard disk more than the specified limit, your hard disk
might be in severe danger.
Your computer data can become corrupted or invalid due to various
reasons, such as: virus infection or attacks, abnormal system
shutdown, accidental cancellation of running program, use of
untrustworthy malware or freeware programs, frequent power failure,
many others. Any of these reasons can play an important role in
corruption, and after that your hard disk becomes unstable and starts
functioning in a proper manner.

Human Errors
The symptoms of human errors cannot be explained.
Solution: Human errors can be avoided by following some simple things which include: avoid
any type of unwanted modification or alteration to the system files, avoid formatting the hard
disk more than its specified limit, and never let any unauthorized person to use your computer in
your absence or even in presence.
Professional Recovery Solution
Above are the few common factors behind hard disk failure. How would you deal with this
situation? Do you have any fix for it? Generally, people recommend data recovery services at the
time of hard disk failure. Such services are provided by data recovery experts for recovering your
data from corrupt/damaged drives. Or you can just do it by yourself. There are many software
companies in the market which provide professional tools for recovering data from hard disk
drives. One of them is SysInfoTools Software, a trustworthy name in the market for providing
