Check Physical Connections
One of the most common reasons an external LaCie drive is beeping and not showing up is because of a loose connection between the drive and the computer. First, check that both ends of the USB or Thunderbolt cable are securely plugged into the LaCie drive and the computer. Unplug both ends and reseat them firmly to ensure a tight connection. [1] If the cable is loose or makes a poor connection, the computer will be unable to detect the external drive.
Also inspect the cable for any damage or bent pins. Try using a different USB or Thunderbolt cable that you know works properly. Cables can sometimes become faulty over time or if they get crimped. Swapping out the cable may resolve the issue if the original cable is defective. Make sure both connectors are oriented correctly when plugging the cable back in.
For desktop users, try plugging the LaCie directly into the rear USB port on the computer itself rather than through a hub. The rear ports are sometimes more reliable. Overall, securely connecting both ends of the cable is often the quick fix when an external drive suddenly stops working or showing up.
Try Different USB Ports
One of the first troubleshooting steps is to connect the LaCie drive to different USB ports on your computer. There could be an issue with the specific USB port you are using that is preventing the drive from being detected.
Try plugging the drive into another USB port on the computer, preferably directly on the motherboard if possible. Avoid connecting it to a USB hub.
According to https://www.stellarinfo.co.in/blog/how-to-fix-external-hard-disk-drive-not-recognized/, USB ports can sometimes become faulty which results in external drives not being recognized. Trying a different USB port bypasses any potential issues with that specific port.
If the LaCie drive is detected in another USB port, the issue is with the original port you were using. You may need to get that USB port serviced if it is malfunctioning. If the drive still fails to show up in other USB ports, there is a different underlying problem.
Update Drivers
One potential cause of an external LaCie drive not showing up is outdated drivers on your computer. Drivers allow your operating system to communicate with connected devices like external hard drives. Over time, drivers can become corrupted or out of date, preventing proper communication with devices. To fix this:
First, update your USB drivers. Navigate to Device Manager, expand the Universal Serial Bus controllers section, right click on each USB device and select Update Driver. Allow Windows to automatically search and install the latest driver software.
You should also update Thunderbolt drivers if your LaCie drive connects via Thunderbolt. Go to Device Manager, right click on any Thunderbolt device and select Update Driver. Follow the on-screen prompts to update to the latest Thunderbolt drivers from Intel.
Updating USB and Thunderbolt drivers can often resolve issues with external drives not being detected. Be sure to restart your computer after updating drivers to allow changes to take effect. Check if the LaCie drive shows up properly after this process. If the drive still does not show, additional troubleshooting steps may be required.
Restart the Computer
One of the simplest fixes you can try if your LaCie drive is not showing up is to fully restart your computer. This clears the cache and resets all connected devices. Shut down your computer – do not just restart it. Make sure the computer is fully powered down for at least 60 seconds before booting it back up. This gives the computer hardware a chance to fully reset.
Once restarted, connect your LaCie drive again and see if it shows up in File Explorer. Sometimes the drive may have gotten stuck or frozen from an improper disconnect or shutdown sequence, and a full restart is required. If the drive still does not show up or continues beeping, move on to other troubleshooting methods.
Check Disk Utility
Open Disk Utility and see if the LaCie drive shows up. Disk Utility is an app included with macOS that allows you to manage internal and external disks. To open Disk Utility:
1. Click the magnifying glass icon in the top right corner of your screen and search for “Disk Utility”.
2. Open the Disk Utility app. This will show all available disks connected to your Mac.
Check if your LaCie external hard drive shows up here. If you can see the drive in Disk Utility but not in Finder, the drive may need to be mounted. Select the LaCie drive and click “Mount” at the top of the Disk Utility window. This should make the drive accessible in Finder.
If the LaCie drive is not appearing at all in Disk Utility, the drive may not be properly connected or turned on. Check the physical connections like the USB cable and power cable. Try connecting the drive to a different USB port as well. The drive may also need a firmware update from LaCie to work properly with your version of macOS.

Change Cables
One of the most common reasons an external hard drive is not being detected is a faulty USB or Thunderbolt cable. The cable connects your drive to your computer, and if there are any issues with the cable itself, the two devices will be unable to communicate properly.
If your LaCie external hard drive is not showing up in File Explorer or Disk Management on your Windows 10 computer, try using a different USB cable that you know works with other devices. Swap the current cable with another high-quality USB 3.0 or USB-C cable that can transfer data. Thunderbolt cables may be used with compatible LaCie drives.
Cables can break down over time due to wear and tear. A damaged cable is likely the issue if your drive is beeping and not showing up on your computer. By using a different cable, you may be able to restore the connection between the drive and your computer.[1]
Try a Different Computer
One troubleshooting step to take is to connect the LaCie drive to a different computer to test if it is detected. This helps determine whether the issue is with the drive itself or a problem with the original computer.
Connect the LaCie drive to another Windows or Mac computer using the USB cable. If the drive is detected on the other computer, then the issue likely lies with the original machine. Potential causes include driver problems, USB port issues, or an operating system error. Checking the drive on a separate computer is an easy way to isolate the cause.
However, if the LaCie drive continues to not be recognized on other computers, then the drive itself is likely experiencing technical problems. This points to a corrupted drive, bad sectors, or physical internal damage. In this case, contacting LaCie technical support or a data recovery service may be required. But first, always check the drive on a different computer before assuming the unit is faulty.
Update LaCie Drive Firmware
One potential solution is to check the LaCie website for any available firmware updates for your specific LaCie drive model and install if available. Firmware is the software programmed on the drive itself that allows it to communicate with your computer. An outdated version can sometimes cause connectivity issues.
To check for and install firmware updates:
- Go to the LaCie support downloads page: https://www.lacie.com/support/downloads/
- Enter your LaCie drive’s serial number to find any available firmware updates.
- Click the firmware update file to download it.
- Follow the instructions to install the new firmware on your LaCie drive.
Updating to the latest firmware can resolve compatibility issues, fix bugs, and improve the overall performance of your LaCie drive. If the drive is still not recognized after the firmware update, you may need to try other troubleshooting steps.
