How to Recover Data from a LaCie External Hard Drive

If you have experienced data loss on your LaCie external hard drive, it is crucial to stop using the drive immediately. Continuing to use the drive can result in new data being written over the areas where your lost files are located, potentially making them unrecoverable.

With the right approach, however, you can often restore your precious files. You have the option of using specialized data recovery software, Time Machine snapshots (for macOS users), or the File History feature (if you’re using a Windows PC). Below are the step-by-step instructions for each method that you can follow to recover your data from the external hard drive.

Method 1: Using Data Recovery Software

Using specialized data recovery software is one of the easiest and most efficient ways of recovering files from a LaCie external hard drive. We prefer this method over the other ones since a tool like this can be helpful in many data loss situations related to accidental deletion, formatting, unexpected disappearance of files, and even file system corruption. And its effectiveness doesn’t depend on whether you have a backup of your drive available or not.

While there are a few data recovery tools to choose from, we recommend Disk Drill since it works on both macOS and Windows platforms and fully supports LaCie drive file system formats (exFAT, NTFS, HFS+, and more). Moreover, it offers an interactive design, making it easy to use for anyone. Another advantage of this tool is that you’ll be able to test it for free to see whether those files can actually be recovered before having to get the paid Pro version.

Regardless of whether you’re on a Mac or Windows, the process for using Disk Drill to recover data from a LaCie hard drive is quite similar. Here’s what you need to do:

  1. Connect your LaCie drive to your computer. Plug your LaCie hard drive into your computer using the appropriate USB or Thunderbolt cable. 
  2. Download Disk Drill for Mac or Windows and follow the onscreen instructions to install it.
  3. Launch Disk Drill. In the Disk Drill dashboard, you will see a list of available storage devices.

  1. Connect your LaCie external drive to your Mac.

Method 3: Using File History on Windows PC

If you’re using a Windows-based PC with your LaCie external hard drive, you might be able to recover the lost data using the File History feature. You need to keep in mind that this option will work only if you’ve previously set up this tool to back up your drive.
Also, with a recent update, Windows has discontinued support for backing up external devices using File History. However, if you created backups prior to this update, your data will remain accessible for recovery purposes.

Follow these steps to recover files from your LaCie drive using File History on Windows:

  1. Using a cable, connect your LaCie hard drive to your PC.
  2. Open your external drive and navigate to the place where previously the deleted files were located.
  3. Right-click inside the folder or disk and click Properties from the drop-down menu.LaCie drive properties button
