How to backup deleted files from hard disk？

Losing important files can be a distressing experience, whether it results from accidental deletion, formatting, malware attacks, or hard disk corruption. However, with the right knowledge and tools, it is possible to back up deleted files from a hard disk before they are permanently lost.

1. File Deletion on a Hard Disk

When a file is deleted from a hard disk, it is not immediately removed from the storage medium. Instead, the operating system marks the space it occupied as available for new data. Until that space is overwritten, the original data remains on the disk and can be recovered.

1.1 Why Files Can Be Recovered

Deleted files remain in the disk’s file system until overwritten.

Most recovery tools scan for data remnants in unallocated space.

1.2 Factors That Influence Recovery Success

Time elapsed since deletion

Disk usage post-deletion

Type of file system (NTFS, FAT32. exFAT, etc.)

Disk health and fragmentation

2. Precautions to Maximize Recovery Chances

To increase your chances of successful recovery:

Stop using the disk immediately to prevent overwriting deleted files.

Avoid writing new data to the same drive where files were deleted.

Use a different drive for downloading and installing recovery software.

Avoid formatting or repartitioning the disk.

3. Choosing the Right Recovery Software

There are many data recovery tools available. When selecting one, consider the following:

Compatibility with your operating system

Support for the file system of your hard disk

Ability to preview files before recovery
