How to Recover Deleted Files from a Hard Drive

How to Recover Deleted Files from a Hard Drive: Losing important files from your hard drive can feel like a nightmare. Whether it’s due to accidental deletion, formatting, or a corrupted partition, the good news is data is often recoverable especially if you act quickly.

How to Recover Deleted Files from a Hard Drive

This comprehensive guide will walk you through how file deletion works, methods to recover deleted files, tools you can use, precautions to avoid overwriting data, and best practices to prevent data loss in the future.

Understanding File Deletion: What Happens When You Delete a File?

When you delete a file from your hard drive, it’s not immediately erased. Instead, your operating system simply marks the space that file occupied as “available” for new data. The file remains intact in the storage until it is overwritten by new data.

This means:

  • The sooner you attempt recovery, the higher the chances of success.
  • Avoid using the drive immediately after deletion to prevent overwriting.

Methods to Recover Deleted Files

There are several ways to recover deleted files, depending on the circumstances:

1. Check the Recycle Bin (Windows) or Trash (macOS)

This is the first step, as most deleted files are temporarily moved here.

Steps (Windows):

  • Open Recycle Bin on the desktop.
  • Right-click the file > Click Restore.

Steps (macOS):

  • Open Trash from the dock.
  • Right-click on the file > Click Put Back.

Works for recently deleted files not permanently removed.

2. Use File History, Time Machine, or Backup Services

If you’ve enabled backup tools, restoring a deleted file is straightforward.

Windows File History

  • Go to the folder where the file was located.
  • Right-click > “Restore previous versions.”

macOS Time Machine

  • Open Time Machine.
  • Navigate to the folder > Select the file > Click Restore.

Cloud Backup Services

Services like OneDrive, Google Drive, Dropbox, or iCloud often keep deleted files in a “trash” folder for 30+ days.

Best for users with backup systems enabled.

3. Use Data Recovery Software

If the file is permanently deleted and no backup is available, specialized recovery software can help.

 How to Use Data Recovery Software:

Example: Using Recuva (Windows)

  1. Download and install Recuva from Piriform’s official site.
  2. Launch the software.
  3. Choose the type of file (documents, pictures, videos).
  4. Select the drive where the file was deleted.
  5. Run a Deep Scan for better results.
  6. Preview and Recover the file to a different storage location.

Success depends on how much data has been written after deletion.

4. Use Command Prompt (Windows)

For users with technical skills, CMD can be used to recover hidden or deleted files (usually from USBs or external drives).

Example:

attrib -h -r -s /s /d X:\*.*

Replace X: with your drive letter.

This command tries to remove hidden/system flags from files that may be recoverable.

Not a guaranteed method. Best combined with recovery tools.

5. Professional Data Recovery Services

If the data is extremely important and software doesn’t work, it’s time to call professionals.

Services like:

  • DriveSavers
  • Ontrack
  • Secure Data Recovery

They use cleanroom environments to extract data from physically or logically damaged drives.

Expensive but often the last resort for critical data.

What NOT to Do After Deletion

To maximize your chances of recovery:

  1. Do NOT install recovery tools on the same drive where data was lost.
  2. Avoid saving new files or browsing heavily.
  3. Do NOT format or repartition the drive.
  4. Don’t use disk-cleaning or optimization software.

Every action increases the chance that the deleted data will be overwritten.

 Recovery from Different Scenarios

Accidental Deletion

  • Use Recycle Bin, backups, or recovery software.

Formatted Drive

  • Use deep-scan capable tools like EaseUS, Disk Drill.

Corrupted/RAW Drive

  • TestDisk or R-Studio can rebuild partitions and recover files.

Virus Attack

  • Run antivirus first.
  • Use recovery tools post-cleanup.

External Drive/USB Recovery

  • Treat it like any hard drive using data recovery software.
  • Run CHKDSK to fix minor file system errors:
chkdsk X: /f

Tips to Improve Recovery Success

  • Act quickly. Time is critical before the deleted space is overwritten.
  • Use reliable tools. Free software is great, but premium tools offer better algorithms.
  • Scan thoroughly. Always use “Deep Scan” mode when offered.
  • Recover to a different drive. Never recover files to the original location.

 How to Prevent Future Data Loss

  1. Use automated backups.
    • Windows File History
    • macOS Time Machine
    • Cloud backups (Google Drive, OneDrive, iCloud)
  2. Enable Recycle Bin protection for all drives.
  3. Avoid risky behavior.
    • Don’t interrupt file transfers.
    • Don’t install unverified software.
  4. Invest in data recovery software pre-emptively.
    • Tools like Disk Drill offer “Recovery Vault” features that increase recoverability.
  5. Keep your hard drive healthy.
    • Check disk regularly using tools like CrystalDiskInfo.
    • Avoid exposing drives to heat, magnets, or physical shocks.

FAQs

Can I recover files deleted months ago?

Possibly. If the space hasn’t been overwritten by new data, software like EaseUS or R-Studio might still recover it.

What’s the best free recovery tool?

Recuva (for Windows) and PhotoRec (for all platforms) are top choices for free recovery. However, they may not handle complex scenarios as well as paid tools.

Is data recovery guaranteed?

No. If the deleted file has been overwritten or the drive is severely damaged, recovery may be impossible. However, using advanced tools or services increases the chance of success.

Can I recover files from a formatted drive?

Yes, but only if the formatting was quick (not a secure erase). Use deep-scan software like EaseUS or Disk Drill for best results.

What happens if I recover to the same drive?

You risk overwriting other deleted files that you haven’t recovered yet. Always recover to a different drive (external or secondary internal drive).

Can I recover data from an SSD?

Yes, but success is lower due to TRIM technology, which instantly clears deleted sectors to optimize speed. Act quickly and avoid heavy usage for best results.

Is it safe to use data recovery software?

Yes if downloaded from trusted sources. Avoid pirated or cracked versions, as they may contain malware.

What about encrypted drives or files?

Recovery is much more complex. You’ll need the encryption key or password. Even then, data may remain inaccessible if corruption occurred.

Can I recover files from a crashed computer?

Yes, by removing the hard drive and connecting it to another machine using a USB-to-SATA adapter or enclosure, then running recovery software.

How much do professional recovery services cost?

It can range from $300 to $3,000+, depending on the damage and urgency. Most services offer a free evaluation and only charge if data is recovered.
