Hard drive failure can result from a variety of causes, but the most common is simply age. As hard drives pass from one year to the next, their internals slowly degrades until they finally stop working entirely. 
Floods and fires can cause tremendous damage to a home or office—damage that can easily extend to connected devices like computers and servers, potentially causing thousands of dollars in damages.

Other causes of hard drive failure include:

Floods and fires can cause tremendous damage to a home or office—damage that can easily extend to connected devices like computers and servers, potentially causing thousands of dollars in damages. This is why it's critical for businesses to protect their most valuable data with comprehensive backup measures, including server-side backup systems.

Businesses Can Protect Data by Backing Up Servers with Server Backup Systems

A server-side backup system protects business data on the entire network—from PCs running Microsoft Windows 7 up to virtual machines (VMs) hosted at remote data centers. The process of creating a server backup is quick, painless, and can be done remotely, so there's no need to visit individual PCs or servers. Even better, server-side backups only require a single button click to restore files from any time within the past 30 days.


Excessive heat can also have a detrimental impact on the components of a hard disk drive. As the temperature rises, disk platters expand and then shrink as the temperature drops. This may lead to a deformed magnetic surface that forms micro-cracks, which is a major issue because it compromises data.

Mechanical Shock

Mechanical shock can occur when general movement, hard drive vibration, or an accident impacts the disk platter that holds the data. Accidental mechanical shock is more common than you might think. A simple knock on a table could cause enough impact to damage the platters especially if it revolves at high speed (most do). Even dropping the computer itself is enough to create significant damage in some cases.
Magnetic fields interfere with how sensitive read/write heads can detect magnetic signals from disk surfaces to write data or read previously stored information in regards to digital photography and video editing. A process is known as "soft demagnetization" occurs when the magnetic field is applied for such a long time that it reduces the ability of the read/write heads to be able to pick out these signals.

Water Damage

Spilling a liquid onto a computer device is almost always bad news. Only in certain gadgets will there be built-in protection against water. The majority of today's consumer goods aren't meant to be barriers against water or other liquids. Water produces unwanted fluctuating electrical current inside your device, which can seriously harm it. Even a drop or two can cause enough interference to destroy your device's circuitry and render it useless.

Electromagnetic Interference

Electromagnetic emissions from devices such as phones, speakers, microwaves, and even other hard drives can impact the performance of an HDD. The electromagnetic emissions produced by one device interfere with the magnetic field used for writing information onto disks, causing "bit rot".

Human Error

We make a lot of the same mistakes. Our clumsiness with a hard disk drive device is no exception. Human error is almost always unintentional (we hope!) and is the most common reason that a hard disk drive fails, whether it's through the deletion of files or a fall.


If you've ever thought about it or even wondered what hard drive recovery was, then know that there are data recovery companies to do this for you. They have the experience and the right tools for this job. If any of your devices fail due to these reasons here are some things to do:
Replace the device if possible Take the device offsite where it's safe Call a professional service company

What else can be done?

This is unfortunately not an easy question with a simple answer because so many factors contribute to data loss. But one thing remains certain – having backed up sensitive information means protecting it from potential damage caused by events such as fires, floods, theft, power surges, and other problems without any added work on your end!
