What is Data Recovery Software?

Data recovery software is a tool that aids users in retrieving and restoring lost data. It offers functionalities for both logical and physical recovery. Logical recovery typically refers to the restoration of data in scenarios such as accidental deletion, incorrect cloning, wrong formatting, partition loss, or virus infections. Physical recovery, on the other hand, pertains to the retrieval of data lost due to hardware physical damage, like stuck motors, bad sectors on a hard drive, unrecognizable hard drives, or misaligned read/write heads.

Data recovery software can be helpful in various scenarios of data loss, including but not limited to: 1. Accidental deletion: Files are lost due to mistakenly using the "Delete" key or emptying the Recycle Bin. 2. Hard drive formatting: Quick or full format of the hard drive results in the loss of all data. 3. System crashes or blue screens: Data becomes inaccessible due to operating system failures, blue screen errors, or inability to boot. 4. Virus attacks: Malware or viruses corrupt the file system, leading to file loss or hiding. 5. Partition issues: Damaged partition tables, lost partitions, or problems during partition resizing. 6. Physical hard drive damage: Bad sectors, motor failure, or other hardware issues make data unreadable. 7. Flash drive/SD card problems: Memory cards or USB flash drives are disconnected unexpectedly, damaged, or become unrecognized. 8. Reinstalling the system: Important files are lost during OS reinstallation without prior backup. 9. RAID array failure: RAID configuration errors or RAID controller failures compromise data integrity. 10. Cloud storage or network share loss: Files are deleted from the cloud or lost due to network connectivity issues. Data recovery software works by scanning for remnants of original data on the disk and attempting to restore deleted, formatted, or corrupted files. However, it's not always guaranteed that 100% of the data can be recovered, so regular backups are essential for prevention.

There are many situations where data recovery software can come in handy. In some severe cases, it may be the only way to get back your lost data. Here are some common examples:

    • Accidental Deletion: If you have accidentally deleted files or folders from your desktop or laptop hard drive, a hard drive recovery software can scan your disk and restore the data.
    • Emptying the Recycle Bin: If you emptied the Recycle Bin before realizing you still needed the files, a Recycle Bin Data Recovery tool might be able to help you retrieve deleted files.
    • Formatting a Drive: If you mistakenly formatted a drive like a USB flash drive, a USB recovery software comes in handy to unformat the drive and recover data promptly.
    • Virus Attack: If your computer is infected with a virus that has deleted or corrupted some files, data recovery software can retrieve lost data from a virus or malware attack.
    • Operating System Crash/Issues: If your operating system crashes or encounters problems, such as Windows 10 not shutting down, Windows Whea Uncorrectable Error, or "Preparing Windows" stuck, and you can't access your data, you would need free data recovery software for Windows 10.

Data recovery software can help retrieve lost or deleted files in such situations. However, it does not guarantee success in all cases. For instance, if the disk is too severely damaged, data may be lost permanently, and data recovery software may fail to restore it. Regardless of the reason, it's always worth trying a data recovery tool before giving up.

How does data recovery software work?

To understand how data recovery software works, you first need to know how computers store files.

How does a hard drive store data?

When we save a file to the hard disk, the system first writes the filename and size into the File Allocation Table, then starts writing the file content from the beginning of the Data Zone according to the free space indicated in the File Allocation Table. Finally, the actual content of the file is written into the Data Zone, completing the storage operation for that file.

How Hard Drive Saves Data

The Working Principle of Data Recovery Software

Data recovery can be defined as the process of accessing information from a storage device that cannot be done through standard means. When we delete a file or perform a formatting operation, the system writes a deletion marker in front of the file in the File Allocation Table (FAT). It clears the FAT, indicating that the file has been deleted and the space it occupied is now free for you to save other files.

Thus, when we delete a file and want to recover it, we just need to use data recovery knowledge and tools to remove the deletion marker. Data recovery software can scan your hard drive for these deleted files and restore them.

What can data recovery software NOT do?

Of course, data-recovery software has its limits.

    If the data has been overwritten, it may be gone for good and impossible to recover. Data recovery software can only retrieve files that were previously saved to a device but have since disappeared. This means you cannot use a file recovery tool to restore an unsaved Word document.

What are the best data recovery software for different operating systems?

There are various data recovery software options available, both free and paid. Which one is the best depends on several factors, such as the type of data you need to recover, the size of your hard drive, the operating system you use, the complexity of the recovery process, and your budget.

To help you decide, we've compiled a list of the best data recovery software for each operating system, based on user reviews and expert opinions. Read on.

Practical Tips for Using Data Recovery Software (Must Read)

After selecting the most suitable data recovery software for you, you can skillfully use it to improve the data recovery rate.

    • After data loss, avoid saving new files to the device where the data was lost, as this may overwrite the data and make it irrecoverable.
    • If you want to recover data from a system disk, don't reinstall or restore the system. Instead, remove the hard drive and connect it as a secondary drive to another computer for recovery.
    • Avoid formatting the disk, as this can compromise the recovery process. While data can be recovered, reformatting makes it more difficult.
    • When a partition has issues and data cannot be accessed, do not check the disk, as it may damage the magic data and increase the difficulty of recovery.
    • Don't directly restore data to the source disk, as this could potentially corrupt the original data.
