How to restore hard disk deleted files

​Losing this data whether due to accidental deletion, formatting errors, or system crashes can feel catastrophic. However, the good news is that deleted files from a hard disk can often be restored with the right approach and tools.

Chapter 1: How File Deletion Works

When you delete a file, it doesn’t vanish from the hard disk instantly. Instead, the operating system marks its space as available for reuse. Until that space is overwritten, the deleted file remains recoverable. This behavior opens a window of opportunity to recover lost data—if you act fast and use the right methods.

Types of File Deletion:

Soft Deletion: Moving files to the Recycle Bin or Trash.

Permanent Deletion: Emptying the Recycle Bin or using Shift + Delete.

Formatting: Quick formatting erases the file table, but data may still be intact.

Corruption or OS Errors: Can cause files to become inaccessible but not truly deleted.

Chapter 2: Preliminary Checks Before Using Software

1. Check the Recycle Bin/Trash

Windows: Open the Recycle Bin and restore files by right-clicking.

macOS: Open the Trash, drag files back to your desktop or preferred folder.

2. Use File History or Time Machine

Windows File History:

Go to Control Panel > File History > Restore personal files.

macOS Time Machine:

Connect your backup disk, open Time Machine, and restore previous versions of files.

3. Recent Files in Cloud Storage

If you use OneDrive, Google Drive, or Dropbox, check the cloud trash or deleted file history.

4. Stop Using the Drive Immediately

Avoid writing new data to the hard disk to prevent overwriting the deleted files.
