Data Recovery of 539 GB Missing Files from an External Hard Drive in Westmount, Quebec

Data recovery became necessary for a customer in Westmount, Quebec, after they accidentally dropped a 1 TB Western Digital external hard drive (model WDGBPU0010BBL-05) while it was still connected to a laptop. Although the fall was only about one foot, the sudden disconnection caused 539 GB of important files to disappear instantly.

Recognizing the seriousness of the situation, the customer contacted WeRecoverData for professional assistance.

The Drive Powered On — But the Files Were Gone

At first, the external drive seemed to function normally. It powered on without issue, appeared in Device Manager and Disk Management, and made no unusual clicking or grinding sounds.

However, when the customer opened File Explorer, most of the data was missing. Documents, photos, videos, and other personal files no longer appeared. The drive looked healthy on the surface, yet Windows could not display the stored content.

This contrast — normal hardware behavior but missing data — suggested a logical rather than mechanical issue.

Initial Troubleshooting Provided No Answers

Before seeking professional help, the customer tried several safe troubleshooting steps:

  • Checked for hidden files

  • Restarted the system

  • Used basic Windows disk utilities

  • Reviewed Disk Management settings

Importantly, the customer did not run third-party recovery software, which helped avoid overwriting potentially recoverable data.

Despite these efforts, the files remained inaccessible. At that point, it was unclear whether the data had been deleted, corrupted, or lost due to the sudden unplugging during the fall.

Rather than risk further damage, the customer chose professional data recovery.

Lab Diagnostics Reveal File System Corruption

When the drive arrived at the WeRecoverData lab, engineers immediately performed a comprehensive diagnostic evaluation.

The hardware tested healthy. The drive showed:

  • No mechanical failure

  • No damaged read/write heads

  • No platter damage

  • Full low-level accessibility

Because the physical components remained intact, engineers shifted their focus to the file system.

They quickly identified the root cause: file system corruption triggered by the abrupt disconnection during the drop. When the drive lost power unexpectedly, it damaged the file index structure. As a result, Windows could no longer properly locate or display the files — even though the raw data still existed on the disk.

Creating a Full Sector-by-Sector Clone

To protect the remaining data, engineers first created a complete sector-by-sector image of the external hard drive.

This step ensured:

  • The original drive remained untouched

  • No additional stress affected the hardware

  • All recovery procedures took place on a forensic-grade clone

By working from the image instead of the original device, the team eliminated the risk of accidental data overwriting.

Bypassing the Corrupted File System

Next, engineers used advanced recovery tools to bypass the damaged file system entirely. Instead of relying on the corrupted directory structure, they scanned the raw data blocks directly.

Almost immediately, recoverable files began to appear.

Technicians located and previewed:

  • Documents and spreadsheets

  • Scanned records

  • Photos

  • Videos

Each file underwent integrity verification to confirm it remained intact and uncorrupted. Because the corruption affected only the file index — not the underlying data — the majority of files remained fully recoverable.

100% of 539 GB Successfully Recovered

After carefully extracting and organizing the data, the team recovered 100% of the missing 539 GB.

Engineers then transferred the restored files to a new, secure external hard drive to ensure safe, reliable access. Before returning the data, they performed final verification checks to confirm all files opened properly.

From Simple Accident to Complete Recovery

Although the drop measured only about one foot, the sudden disconnection caused significant file system damage. What appeared at first to be catastrophic data loss ultimately turned out to be a recoverable logical failure.

Thanks to professional tools and controlled lab procedures, the customer received all missing data fully restored.

Professional Recovery for Dropped and Corrupted Drives

At WeRecoverData, specialists handle cases involving:

  • Dropped external hard drives

  • Accidental unplugging

  • File system corruption

  • Missing or invisible files

  • Western Digital drive issues

Even when a drive powers on normally, hidden logical damage can prevent access to critical files. In these situations, professional evaluation and recovery techniques make the difference between permanent loss and full restoration.

WeRecoverData remains committed to recovering what matters most — quickly, safely, and completely.
