What is Data Recovery Software? How It Works & When to Use It

Data recovery software is a computer program built to find and restore files you thought were gone. Now you might wonder what’s special about it because even Windows has a recovery utility to get back the deleted files. What distinguishes the data recovery tools is how it is made. It is designed to bypass the standard operating system restrictions to perform a raw sector-by-sector scan of your drive. 

In this article, we will see in depth what is data recovery software and how it works to recover your deleted files. We will also see the top data recovery solutions in the market, explaining to you when to use one.

Understanding the Basics: What is Data Recovery Software?

Data recovery software is a digital tool specifically designed to restore lost, deleted, corrupted, or inaccessible files from various storage devices (like SSDs, HDDs, USB, local storage, etc.). When a file is removed for any reason, the operating system removes its pointer and marks the space as available. The actual data still remains there. The data recovery software scans these storage devices and finds the remnants of the files. Thus, reconstructing them into readable formats. 

But remember, the success of data recovery through software depends on the drive’s physical health. If a drive suffers mechanical failure or the data is completely overwritten, the software cannot retrieve it.

How Data Recovery Software Works?

When you delete a file, your phone, computer, or PC does not actually destroy it. Every storage device – like your computer’s hard drive or a USB stick – is divided into millions of tiny storage pockets called sectors. To keep track of everything, it uses a filesystem. Data recovery software goes into the file systems and tracks the data remnants to reconstruct them. This is called raw recovery, and that’s how file recovery works.

The Step-by-Step Data Recovery Process

Now let’s look in detail at how the data recovery process works. Different data recovery tools are built on different algorithms yet follow the same principle. Deleted or lost data cannot just vanish; its index is deleted that point to the data stored, which reflects the space as empty.

Note: Data remains on the storage drive until it is overwritten.

Data recovery process steps:

1. Scan Storage Device

The first step is scanning the storage device for any remaining metadata (which includes file names, paths, sizes, and dates files were modified). This information is used in later steps to reconstruct the files.

2. Detect Signatures

File signatures are the fixed sequence of bytes at the start and the end of the files, which can be viewed using a hex editor. The software scans and detects the signature of the deleted data. This tells about the file type and helps to recover them.

3. Identify Signatures

Here comes the file carving. This is the forensic technique used to recover files solely on the basis of intrinsic data without the file system, because the file system is deleted when the file is deleted.

4. Reconstruct Files

The last step is file reconstruction, which involves building the file again with the remnants found. This is the crucial step that determines the recovery success rate of the specific data recovery tool.

This is how your deleted files are recovered based on the information found by the recovery software. Also, note that for blocked-access data where the files are encrypted, the data recovery tool needs the decryption password, key, or other details to access its content.

Note: Cloud data keeps the user’s data in remote locations and is not recoverable by the data recovery software until the data was previously there on the storage device and was not overwritten.

When to Use Data Recovery Software (and When to Avoid It)

Should you download recovery software or pay for professional help? The wrong choice means complete data loss permanently. In some cases, data recovery tools may not be enough to restore deleted or lost data. That’s where data recovery services come in.

Data recovery is only possible through software when the drive is not physically damaged. Physical damage may include header dislocation, head crash, water or liquid damage, and platter damage. Though a data recovery solution might work in formatted or corrupted situations, it is not advised to use the software in physically damaged situations.

Quick comparison table for when to use data recovery software and when to avoid it and use data recovery services:

Use Data Recovery Software	Use Professional Recovery Service
The drive is detected with the correct capacity.	Your drive is physically damaged.
The drive doesn’t make unusual noises.	You hear clicking or beeping sounds from the hard drive.
You accidentally formatted the wrong drive.	The drive is not detected at all.
You accidentally deleted the wrong files.	Software made things worse.
You emptied the recycle bin.
Virus attack

Note: If you formatted an SSD, TRIM is triggered, which means data recovery is less likely.

Quick decision flowchart

Does your drive make any unusual sound or noise?
No | The data recovery software may work	Yes, clicking or beeping sound | Need professional recovery service

Is the drive detected at the correct capacity?
Yes | The data recovery software may work	No, not detected, or detected with wrong capacity | Need professional recovery service

Reason for data loss?
Formatting/ accidental deletion/ corruption/ virus attack | The data recovery software may work	Drop/ water/ unknown | Need professional recovery service

Why software can’t fix mechanical failures

The data recovery software works by reading the drive and reconstructing the file structures. If the drive is broken or damaged, the drive cannot be read properly, and the software is useless.

Note: Running the data recovery software on the damaged drive can even worsen the case, causing further damage.

Choosing the Best Data Recovery Software

As you research the best data recovery software, you’ll find many options. It is important to choose software with all the required features because making the wrong choice can lead to permanent data deletion and put your information at risk.

Key Features to Look For While Choosing Data Recovery Software

There are some non-negotiable features to check in the recovery software before making a decision. Here is the quick checklist for choosing the best data recovery tool.

• File Type Support: Check the data recovery software for your specific type of file recovery. Most software comes with all the common file types for recovery, such as photos, videos, documents, audio, emails, and archives.
• Scanning Modes: Data recovery software mostly includes Quick Scan and Deep Scan. Quick Scan relies on file structures that still exist, while Deep Scan ignores the file system completely and scans the disk sector by sector.
• Preview Feature: The preview feature helps in checking the file integrity before it is recovered. This usually saves time and helps in selective data recovery.
• User-Friendly UI: The software that is easier to use is obviously the most preferred. For software with a user-friendly UI, you don’t have to spend time learning the technicalities of the software and can directly begin the recovery process.
• Price/Demo/Trial: Prices vary with features. Look for transparent pricing software with lifelong licences. Also, try the demo version of the software to check its ease and performance.
