• Firmware or manufacturer faults, its caused by improper voltage, accidental shutdown,
interruption during firmware upgrade and manufacturing faults
• Electronic failure or power surge. Sometimes, UPS is unable to deliver the required
power supply. It’s either too high or too slow. This can also occur when you use an
unreliable power source or there is frequent interruption in the flow of electricity.
• Overheating. This error may occur due to faulty CPU fan, improper ventilation, high voltage
power supply, high temperature, virus infection and development of bad sectors.
This reasons could heat up the system and lead o sudden hard disk failure.
• Mechanical or internal failure. It can occur due to moving parts, malware or virus attack,
bad sectors, improper power supply and so on. These reasons could lead to hard drive
failure or damage and data corruption.
• Corrupt file. Use of malicious or faulty apps, accidental closure of running programs,
unethical way of shutting down the PC, power surges etc. are reasons that lead to system
file corruption and make the hard disk inaccessible.
• Human errors. They are the most common cause of hard disk failure. Such errors may
include modifying system registry settings, wrong installations of OS, alteration in
system files attributes, accidental deletion of files or directories, etc. these type of errors
are quite hard to repair. Human errors might not only cause severe damage to hard disk,
but could also lead to permanent data loss. Hence, to scan on advance level, and recover
data from damaged or failed hard drive, proceed with the most efficient data recovery
software.
• Water damage. Your computer, laptop or hard-drive is not water resistant. All of them are
electronic components which can crash when water reaches inside them. While the
system is ON or even if it is OFF, if water accidentally reaches inside the hard-drive, it
will be crashed.
• Virus or faulty software. A software is capable to corrupt the system or data going inside
hard-drive but they are not designed to do that. So, when software work normally, they
won’t create any problem but if due to some update, an unexpected closing of the
program, incompatibility with software or hardware, if any issue comes in software or it’s
working then it can corrupt the hard drive and/or crash it. If your system in infected with
viruses or you’ve installed any malicious software they might corrupt your hard-drive data,
lock it or crash hard-drive then if you are not quick to stop them, they will do this.
• Unallocated space issue. Sometimes, due to some flaws in the system or at the boot time,
a portion of hard-drive storage space is lost. It becomes unreachable and you don’t know
whether those sectors of your hard drive are corrupted and data inside them is
permanently lost or it’s still available there. This is another very frequent cause of hard drive
failure. Usually, it only makes a portion of hard-drive inaccessible but in some
cases, it can cause the loss of Windows directory files which don’t let the system to work
as required as Windows system files are inaccessible.
