What is Data Recovery?

Data recovery is a procedure to recover data from a computer’s hard drive that has been lost due to a system failure or mechanical malfunction. 

Data recovery software is used to recover data that has been accidentally overwritten or deleted from a computer.  Many companies and individuals specialize in data recovery and programs who can extract data from computers hard drives which is lost recently due to some machine or human error.


The method used to recover this data depends on the type of damage; in cases of physical and logical damage, several ways are used to deal with the physical damage first and the logical damage second.

Physical damage often leads to logical damage; for example, when a hard drive overheats, it causes programs to malfunction and eventually causes the operating system to fail. The primary function of data recovery software is to recover data from a damaged hard drive or operating system. 

Data recovery involves using different methods to intervene on a computer’s hard drive and recover lost, deleted, or compromised files. These failures refer to physical and logical damage. 


There are various techniques used in data recovery. Hardware replacement is probably the easiest and cheapest method of data recovery. One of the problems with these programs is that they will often permanently delete corrupted files automatically.

Recovery software is available for different forms of data recovery on systems that are still somewhat operable or for operating systems that have failed.

If a fan is broken and the hard drive overheats, causing a malfunction, simply replacing a part solves the problem. This technique is not always reliable, it can sometimes cause more damage to an operating system by rewriting sectors, and it is not capable of recovering all the data. 

It often bypasses the operating system and goes directly to the hard drive. This technique takes the data image from the damaged hard drive partition and transfers it to a stable partition. Disk images are used when a hard disk has been physically damaged. 

File restore is done when the damage is strictly logical, and the operating system is still working. Most data recovery software specialists first check for hardware damage before moving on to more expensive and time-consuming forms of data recovery.

Sometimes those strategies are used individually or with different techniques, depending on the type of hard drive damage and the amount of money we are willing to spend to recover data.

Most computer manufacturers provide data recovery software out of the box with new features, which allows the system to check for lost or corrupted data in a system failure. 

Data grinding is done by data recovery software specialists and is going to each section of a hard drive and looking for specific files. This method is costly and time-consuming.


Professional data recovery software is costly and time-consuming, so many users try to recover the data themselves. 

There are many tips on the internet to recover data, including freezing, tap, dropping, and spin the hard drive. 

Although some of these procedures may work from time to time, they further damage the hard drive and often lose data permanently. 

Keep in mind that removing the hard drive from your computer will often void your warranty and cost you more in the long run. 

Another misconception regarding data recovery software is that everything is saved somewhere on a hard drive and can eventually be recovered.

This is not true. A scratch on the hard drive can instantly erase data permanently, and you will overwrite the computer. 

Although data recovery software can often recover most lost data, never assume that everything is salvageable.


The best data recovery software is one that you can perform on your own a data backup. Backing up files regularly can be a lifesaver; ask any college student who has missed a job a couple of days before it is due. 

Get in the habit of saving documents twice, once to your hard drive and a portable memory device. 

There are also several companies online that automatically back up your data either daily, weekly, or monthly. 

The data is encrypted and stored for you and is recoverable from any Internet connection and sometimes from a mobile device.

Warning signs

Sometimes computers crash suddenly for no reason, removing primary data and files without any warning. 

However, there are usually warning signs that a system is about to fail, allowing you to back up your data. 

Warning signs may include slow, and shutdown startup, freezing, sudden unexpected shutdown, programs stop or malfunction, loud noises while the computer is running, or overheating even fan is constantly running.
