How Does Data Recovery Software Work 

How does data recovery software work? This is a question you will need answers to, especially when you accidentally delete a file or your computer crashes. This software scans your computer for deleted files and recovers them if possible. 

There are many different types of data recovery software, but they all work similarly. They aren’t magic – they are just programs that find the data you need from your computer or storage device that is not working and extract it for you. 

In this article, we’ll take you through the working process of data recovery software but before that, let’s first find out,

What Is Data Recovery?

Data recovery is retrieving lost or deleted data from a storage device or computer. You can lose data in various ways, including accidental deletion, corruption from power outages, and viruses. 

Many different types of professional data recovery software can be used to recover lost data. These include software like Stellar Data Recovery. 

The entire process is not always easy or cost-effective, and extra care should be taken when storing sensitive data on external drives or directly on the computer’s hard drive. 

It is essential to take frequent backups of important files to ensure that you can always recover them in the event of a data loss.

How Does It Work?

All data stored in media devices like SD cards, SSDs, HDDs, USB flash drives, and so on are strings of binary digits of 0s and 1s. The strings form text files, audio, video, and photos.

CPU processes these binary digits and presents them to a computer screen in a format we can read and understand.

However, there are chances of getting these storage devices corrupted, which may lead to data loss. Due to human error, you can also accidentally delete some files from your computer. 

When you delete a file from your computer, it gets sent to the recycle bin. You can recover it from here if need be. 

When the recycle bin is emptied, it can be tricky to recover as the files will seem completely gone, but it is not impossible.

When you empty your recycle bin, the master file reference table, which is a pointer pointing to your data’s location in the drive, is deleted.

A file with a pointer can be seen on your monitor, while on the other hand, a file with no pointer cannot be seen.  

This is because there is no pointer reference to locate your file in the storage media, and thus cannot be displayed although it’s still physically in your drive. 

It is important to note that deletion only deletes the pointer and not the actual file in the storage. And if the space is not overwritten, your files can be found and recovered, which is the basis of how data recovery works. 

The trick is to perform the data recovery process as soon as possible since your OS is constantly writing data on your drive, and you might risk overwriting your data.

Data Recovery Software

These tools will often fall under the following four categories:

1. Free 

Free data recovery software, as the name suggests, is free of charge and, as a result, is used by many people. With the free data recovery software you can recover data upto 1GB for free using Stellar Data Recovery.

2. Paid

With paid software, you will pay a fee to access their services. They are updated frequently and have a support team in place if you need further assistance.

3. Beginners software

They are easy to use and feature a user-friendly interface. If you are inexperienced, this could be your right category, as it will guide you through recovering your data so that you don’t get confused.

4. Professional software

They have sophisticated functionality that can detect many file formats and work with hundreds of file formats. 

It is more difficult to use and may be operated from a command-line interface. This software best suits experienced users who know what they are trying to do.

Why Data Recovery Is Necessary

Data recovery can help restore photos, videos, documents, emails, and other important files you may have accidentally deleted. 

It can also help you recover data after a computer crash or a software glitch. This can save you a lot of trouble, especially if your work documents are on the line.

Data Recovery Is Not Always The Best Solution

Data recovery software is not a cure-all. If your computer has been hacked, you can’t just download a data recovery program and expect to get your files back. 

Likewise, if you’ve been the victim of ransomware, a data recovery program, in some cases, may not be the best solution. 

And most importantly, data recovery doesn’t guarantee 100% recovery of your files; the best software may offer up to 97+ %, which is good compared to nothing. 

And keeping in mind that some of these services are very expensive, you should only consider it if the files you risk losing are worth it!

How Long Does Data Recovery Take?

Data recovery can take anywhere between 1 to 5 days, depending on the complexity of the problem. 

The length of time will depend on several factors, including the type and condition of the drive. However, most data recovery projects can be done in less than three days.


How does data recovery software work? You now have an idea. Data recovery is a great way to save your data if you ever face an accident or loss. But make sure you need it before you opt for a data recovery solution. 

It would be best if you tried to understand what the problem is and get in touch with the people who can help you out with the problem.

And don’t forget – data recovery software is not always the best solution. You should also understand the limits of these solutions to make informed decisions about whether you need them. 

And remember that it may not work every time. Some files are just beyond the grasp of any data recovery software.
