LaCie External Hard Drive Troubleshooting Tips

If data loss was caused by corruption (from malware and other logical issues), your hard drive will remain in that state after recovering your data. In most cases, you can fix the issues and make your drive usable again. Here are simple repair methods you can do yourself:

We highly recommend that you secure your data before attempting to fix your drive. Data loss is often unavailable during repair. Use data recovery software to restore your data first or create an image backup and store it somewhere safe.
  • Using Disk Utility (First Aid) – Disk Utility is a built-in macOS disk management app. It has a tool called First Aid, which can scan your drive for errors and attempt to fix them. You can find Disk Utility in Finder > Applications > Utilities.
  • Using S.M.A.R.T. – “Self-Monitoring, Analysis, and Reporting Technology” is a tool that checks your drive for indicators of potential failure. It can’t directly fix errors, but it can try to diagnose the issue so you can find the right solution. It can also provide early warnings so you have time to secure your data and repair the drive. Disk utility has a basic S.M.A.R.T. tool while Disk Drill (and many other disk-related software) offers this feature for free.
  • Formatting the hard drive – If the above solutions don’t work, your last resort is to format the hard drive. Formatting gets rid of everything on the disk – including whatever is causing the corruption. However, note that your data will be deleted as well. A Quick Format makes it easier for data recovery software to restore data, but it’s not always a guarantee.
Even if the repair attempt was a success, we recommend that you no longer use the drive for highly important data. Drives that have already malfunctioned in some way are more prone to issues than healthy drives.


You can check your macOS setting in System Preferences and ensure the external disks option is ticked. If this won’t work, you can try booting in safe mode. If it is not applicable, you may try to rebuild the HFS tree by executing the command in Single User Mode.

sudo fsck_hfs -f /dev/[diskname]

To access files on your LaCie hard drive, Open the Finder, then find your external drive on the side panel. Click it, and your files will be located there.

If your hard drive does not appear on the side panel, you can change the settings of the Finder. To do that, go to open Finder > Preferences > Sidebar. On the list, make sure to tick External Disks.

Make sure that your external hard drive is properly mounted on the port. If data is still inaccessible, try resetting NVRAM and SMC, First Aid, or formatting your device. However, the most recommended way is to use data recovery software applications such as the Disk Drill, which can recover files LaCie external hard drive on Mac, even if it’s corrupted. In this way, your corrupted files will not go to waste, instead, they can be retrieved with no damage to the data itself. Disk Drill is the most user-friendly, flexible, and convenient data recovery software application; you can use its basic version for free.

If your hard drive does not appear on desktop or Finder, check the presence of the disk in Disk Utility. If it’s displayed there, check Finder’s settings and adjust it so you can see the hard drive. If it’s still not working, use First Aid, Disk Drill, or reformat your hard drive.

However, if the hard drive is not even appearing in the Disk Utility, you can use a different port, disable various switches during boot, reset NVRAM and SMC. If these methods don’t work, most likely you will completely lose access to your hard drive and the only way is to use a file recovery service.


In this article, you learned about the most common causes of data loss from your LaCie external hard drives and the primary methods on how to recover them. Data recovery can be costly, so we must take precautions to prevent data loss. We hope this will help you save your data.
