Option 2. Do Basic Checks

In most cases, small problems like a damaged USB cable or unstable power supply are why LaCie does not show up on Mac. Therefore, you should first run some basic checks before trying other options to fix the problem. The common basic checks you should do are:

  • Ensure the drive is plugged incorrectly. It is obvious that if your LaCie hard drive isn't properly plugged in, it won't show up. So, look at your external hard drive connections or reinsert your LaCie drive to your Mac ports. 
  • Damaged cable. If your cable is wobbly or loose, it can disturb the connection between external drives and Mac. Try to connect your LaCie drive to your Mac using a different cable. 
  • Faulty flash drive port. If connection or cable isn't the problem, it must be a hardware issue with your Mac. You should try to connect the hard drive to another port or repair the damaged one. 
  • Reboot your computer. Sometimes MacOS is the culprit. In that case, you can restart your Mac to fix the damaged data. Go to Apple menu > Restart, and this will MacOS memory and give a fresh start to your Mac. 
  • Wrongly formatted drive. If your LaCie hard drive isn't formatted to work with Mac, it can cause you a problem. You should connect your hard drive with your Windows computer to check if it's working on it. 
  • Mac's not formatted to show external hard drives. It is possible that Mac has recognized the LaCie drive but just not showing its icon on the desktop screen. In that case, you can access your drive under the left-side column of the Finder menu. 
  • Reset NVRAM. For this, restart your Mac, press these four keys together for 20 seconds - Option, Command, P, and R. Once your Mac starts again, release all the keys when you hear the startup chime. This might now show a hard drive on your Mac. 
  • Check Apple's Disk Utility. To do so, go to System Preferences > Disk Utility. If the LaCie drive is visible there, click on the option to Mount. This will make the external drive visible on the desktop.
