LaCie External HDD/SSD Not Mounting on Mac?
If a LaCie hard drive doesn't mount on your Mac, it doesn't appear in Finder. You can't use the drive to move files or make backups. Several things, such as physical damage, program conflicts, or damaged file systems, can lead to this problem.
๐Preliminary Checks
Check the Physical Connections
The first thing you should do to fix the problem is ensure that the connections between your LaCie hard drive and your Mac are safe.
- USB/Thunderbolt Cable: Ensure the cord is securely attached to the drive and your Mac. A loose connection can sometimes make it impossible to place the drive.
- Power Supply: If your LaCie drive needs an external power source, ensure it is connected correctly and the power light is on.
Try a Different USB/Thunderbolt Port
The problem might be with the port you are using sometimes. To rule out problems with the port, connect your LaCie hard drive to a different USB or Thunderbolt port on your Mac.
Test with Another Computer
Connect the drive to a different computer to see if the issue is only with your Mac or the LaCie drive. A problem with your Mac is most likely to blame if it mounts right on another computer.
Fix LaCie Drive Not Mounting on Mac
๐#1 Check Disk Utility
Mac OS has a Disk Utility tool to help you control your drives and fix problems.
- Open Disk Utility: Disk Utility is in the "Apps > Utilities folder."
- Locate Your Drive: Find your LaCie drive in the list on the left. If it shows up but isn't mounted, you can try to mount it by hand by choosing the drive and hitting the "Mount" button.
๐#2 Run First Aid in Disk Utility
If you can see your LaCie drive in Disk Utility, but it still won't mount, running First Aid might help fix the problem.
- Select the Drive: You can find your LaCie drive in Disk Utility.
- Run First Aid: Select the "First Aid" button and click "Run." This process will look for disk problems and try to fix them.
๐#3 Reset NVRAM/PRAM/SMC
NVRAM or PRAM (Parameter RAM) is a type of memory that doesn't lose its data when you turn off your Mac. Sometimes, mounting problems can be fixed by resetting it.
- Turn Off Your Mac: Completely shut down your Mac.
- Press and hold the keys to turn it on: As soon as your Mac turns on, hold down the Command, Option, P, and R keys.
- Release the Keys: Press and hold the keys for 20 seconds, then let go. Your Mac will start up again.
The System Management Controller (SMC) controls your Mac's hardware. Resetting it might help if the hardware is having problems.
- Turn Off Your Mac: Shut down your Mac.
- Unplug and Reconnect Power: Take the power charger out of your MacBook and then plug it back in. Take the power cord from your desktop Mac and plug it back in.
- Reset SMC: For MacBooks with batteries that can't be taken out.
- Hold down the power button and the Shift, Control, and Option keys on the left side of the computer at the same time for 10 seconds. Then let go.
- For Desktop Macs: Remove the power line, wait 15 seconds, then put it back in and wait 5 seconds more. Then, turn it on.
๐#4 Change macOS Drive Finder Settings
Users of macOS can choose to show or hide external devices on the desktop and in the Finder menu. Disk Utility may show that your drive is mounted, which could be the problem. To get to these choices, follow these steps:
Step 1: Startup Finder. Select Finder > Settings from the Apple menu bar.
Step 2: Check the box next to "External disks" on the "General" tab.
Step 3: On the "Sidebar" tab, check the box next to "External disks" under "Locations."
