Why Is My LaCie Hard Drive Isn't Showing Up on Mac

Plugging in your hard drive and having your Mac not respond to it whatsoever can be a nightmare, primarily if you use the drive to store cherished photos and videos, important documents, and other files.

However, while your LaCie hard drive not showing up on Mac can be concerning, there's usually a simple cause with a simple solution.

Some of the most common reasons LaCie doesn't show up on Mac include:

Reason Explanation Solution
Damaged cables Loose or otherwise damaged cables that don't connect to the ports properly. Use Different Cables or Clean the Ports
Preferences Settings By default, your Mac might not be configured to show external drives, making it seem like the drive isn't recognized. Set Up Finder Preferences
Improper mounting The cable is connected, but the device doesn't show up in Finder. Mount LaCie Hard Drive Through Disk Utility
Corrupted or damaged drive A corrupted or damaged LaCie drive can't be recognized by a Mac due to file system errors, bad sectors, partition table corruption, or firmware issues. These problems can result from improper ejection, power surges, or physical damage.
Poorly-formatted drive Your Mac might not be able to read the file system on the LaCie drive. If the drive is formatted with EXT4, you'll need additional software to read it on a Mac. You can reformat the drive to a compatible file system, such as exFAT, APFS, or HFS+. (Re)format the Lacie Drive
NVRAM issues NVRAM is a small amount of memory that stores certain settings, such as audio volume, display resolution, and peripheral device configurations, which are accessed by the computer during startup. If the NVRAM becomes corrupted or contains incorrect settings, it might lead to issues recognizing or accessing connected external drives like your LaCie hard drive. Reset NVRAM on Mac

More often than not, it's also possible that there's a random glitch that leads to your Mac not recognizing the LaCie external hard drive. You might even have an unstable power supply that's temporarily causing issues.

In most instances, you can quickly solve the issue and continue using your hard drive as usual.

Perform Basic Checks if LaCie Doesn't Show Up on a Mac

Although most solutions to your LaCie disk not showing up on Mac are relatively straightforward, it's best not to rush to apply them. After all, if the problem is random, such as a damaged cable, you'd only be wasting time and effort trying to format your drive, for instance.

So, to save time and ensure that you don't make matters worse, it's always in your best interest to first perform a few basic checks when you encounter the glitch of your LaCie not connecting to Mac.

  • First, inspect the cable. If it's damaged or loose, your drive won't be able to establish a stable connection with your Mac, leading to your computer not recognizing the device. While at it, check the ports, as any accumulated dust or debris could be causing connection issues.
  • Also, try rebooting your Mac or connecting your drive to another computer to check if it recognizes your LaCie.
  • Of course, you should also do a brief visual inspection of the drive. Even if it's the damage-resistant LaCie Rugged that's not showing up on Mac, it could be that there's still some physical damage on the device preventing it from working correctly. So, look it over and see if there are any signs of damage.

Recover Your Data Before Trying the Fixes

Before you try any of the fixes to your LaCie drive not showing up on Mac, you should try to access and recover any stored data. Otherwise, you might risk losing your data for good.

How To Fix LaCie Drive Not Showing Up on Mac

If you've performed the basic checks and recovered all essential files through Disk Utility and Wondershare Recoverit, and your LaCie hard drive still won't connect to your Mac, here are the top solutions you could try.

Way 1. Set Up Finder Preferences

When everything's working fine, you can always locate your LaCie and other connected devices in Finder. If your device isn't in Finder, you might need to change your Finder Preferences.

You can perform this fix in three easy steps:

  1. Go to Finder > Finder Preferences.
  2. Uncheck External disks in the General tab.
    show external disks on the desktop
  3. Go to the Sidebar tab and check all folders and devices you want to see in Finder.
    show external disk in sidebar

If the problem was in your Finder Preferences, following these steps should get your Mac to recognize your LaCie external hard drive.

Way 2. Check if the Device Is Mounted

It's easy to assume that your LaCie external hard drive is correctly mounted if you've connected it to your Mac via a cable. However, that's not always the case.

To properly mount your device, check the physical connections first to ensure you've plugged the cables correctly. Then, you'll want to visit your Disk Utility:

  1. Go to Finder > Applications > Utilities > Disk Utility.
  2. Select your LaCie external device.
  3. Click Mount.
    mount the lacie disk to mac

After you exit Disk Utility, you should find your LaCie hard drive in Finder if improper mounting was the issue.

Way 3. Run First Aid to Fix LaCie Not Showing Up

While improper mounting or wrong formatting are the more common issues causing the “LaCie hard drive not recognized on Mac” problem, you could also deal with disk corrupted or bad sectors. You can solve this issue by running First Aid.

  1. Go to Finder > Applications > Utilities > Disk Utility.
  2. Select your LaCie device and go to the First Aid tab.
  3. Click Run.
    run first aid to repair lacie

Running First Aid should repair any errors causing your Mac not to recognize your Lacie disk. However, a prerequisite is that the device shows up in your Disk Utility.

Way 4. Use Terminal to Fix LaCie Not Recognized by Mac

If your problems persist, using Terminal could help you get your drive to function normally. While it does involve running a few commands, which might seem complicated at first glance, it's a simple process that anyone can follow:

  1. Go to Finder > Applications > Utilities > Terminal.
  2. Once the Terminal opens, type diskutil list and press Enter to run the command.
    terminal list disk commands
  3. Locate dev/disk[number assigned to your LaCie drive] (external, physical).
  4. Type diskutil info disk[number] and press Enter.
  5. Type diskutil eject disk[number] and press Enter.
  6. Run the diskutil list command.

Once you run the eject command, your LaCie should no longer appear on the diskutil list in Terminal. You can now disconnect and reconnect the device to see if you fixed the problem.

Way 5. Format the Drive to the Right Mac File System

Your device might have the NTFS format—a file system exclusive to Windows. Since Mac devices don't support this file system, you might encounter issues with your LaCie external drive not showing up on Mac.

Note: Keep in mind that formatting the drive will erase all existing data on it. Before formatting, make sure to back up any important data you have on the Lacie drive, or use data recovery software to recover your files if the drive is still accessible on another computer.

Here's how to format the LaCie hard drive after backing up the data:

  1. Go to Finder > Applications > Utilities > Disk Utility.
  2. Find your LaCie external drive and select Info.
  3. Under File System, check if the HDD has a Windows (NTFS) format.
    file system information
  4. Return to Disk Utility > Erase.
  5. Select a Mac compatible format, such as APFS, HFS+, FAT, or exFAT, and click Erase.

Give your Mac a few minutes to complete formatting your LaCie hard drive. When the process is complete, the HDD should be in a format your Mac can recognize.

Way 6. Reset NVRAM on Your Mac

Finally, you can try fixing your LaCie hard drive that won't show up on Mac by resetting your NVRAM. NVRAM, aka non-volatile random-access memory, retains data even when there's no power to the memory chips, and it could sometimes cause glitches.

To reset your NVRAM, you'll need to:

  1. Turn off your Mac.
  2. Hold the Option, Command, P, and R keys for approximately 20 seconds.
  3. Release the keys when you hear the startup chime.

These simple steps will reset your NVRAM and hopefully help you eliminate the glitch causing your LaCie not to show up on Mac.

Final Words

While having your LaCie not show up on Mac when you plug it in can be frightening, it doesn't necessarily mean that your drive is dead or your data has been lost. Try the solutions above to eliminate the problem and protect your data by recovering it using Wondershare Recoverit.
