How to Retrieve Lost Data from an External Hard Drive: Step-by-Step Guide

We generally treat the external hard drive as a digital vault, filled with priceless documents, memories, and important files. But imagine one day you open your vault and everything is gone!

Your data and memories are all lost, and the panic that will knock your door can be very scary. But you don’t need to worry because whatever may be the reason for data loss, it is not truly gone.

No matter if data is deleted accidentally or is gone due to drive failure, it can be recovered until overwritten, i.e., most of the time, data is just hidden or misplaced within the system rather than truly deleted. 

So, if you take the right steps, recovery is possible and assured. In this guide, we will walk you through all the methods to bring your lost data back to life. Let’s get started for the same. 

Quick Fixes: Try These Simple Steps First!

Before turning to advanced recovery methods, try these quick troubleshooting steps:

  1. Reconnect & Switch Ports – A simple unplug-replug might do the trick.
  2. Use Another Computer – Sometimes, the issue is with your PC, not the drive.
  3. Swap Cables – A damaged USB cable can prevent proper detection.
  4. Assign a Drive Letter – Go to Disk Management and manually assign a letter if the drive isn’t showing up.
  5. Check for Hidden Files – In File Explorer, enable ‘Show Hidden Items’ to reveal hidden data.

If none of these work, let’s move on to more advanced recovery techniques.

Recovering Files from Backups: Your Safety Net

If you regularly back up your data, recovery is a breeze. Here’s how:

  • Windows File History – Navigate to Control Panel > File History > Restore Personal Files.
  • Cloud Storage – If you use OneDrive, Google Drive, or Dropbox, check your deleted files folder.
  • External Backup Devices – If you have a separate backup drive, copy your files back.

No backup? Don’t worry! There are other ways to retrieve your lost data.

Command Prompt Magic: Using Windows CMD for Recovery

For tech-savvy users, Windows’ built-in command tools can be a lifesaver:

Method 1: CHKDSK for File System Errors

  1. Open Command Prompt as Administrator.
  2. Type chkdsk X: /f (replace ‘X’ with your drive letter) and press Enter.
  3. Wait for the process to fix any errors.
