7 solutions to Seagate Backup Plus not mounting/working on Mac

For some reason, Seagate external hard drives could not be recognized by Mac. If you can't mount the Seagate Backup Plus drive in Disk Utility, the hard drive won't work on Mac. And you can't access the data stored on it. So it's very urgent to fix the problem to make it work again.

Here are solutions to the Seagate Backup Plus not working or mounting issue.

• 1. Basic checks like the USB cable, USB port, and power resource.
• 2. Check whether the Seagate Backup Plus is showing up in Disk Utility
• 3. Check if the Seagate Backup Plus drive is mounted in Disk Utility
• 4. Show the Seagate Backup Plus on the desktop
• 5. Repair Seagate Backup Plus drive via First Aid
• 6. Update the software on Mac
• 7. Fix the not mounting or working Seagate Backup Plus drive by reformatting

1. Have some basic checks

Sometimes, the Seagate Backup Plus drive won't mount on Mac is due to the bad USB port or cable. Thus, once the Seagate Backup Plus drive stops working, you can first do some routine checks as below.

• Step 1. Check if the cable of the Seagate Backup Plus drive is connected properly to your Mac
  If the drive isn't properly plugged in, it will fail to mount as it received not enough or even no power.
• Step 2. Make sure the USB cable is not at fault
  Try using a different USB cable to see if that fixes the problem.
• Step 3. Check if the USB port is damaged
  Plug the Seagate Backup Plus into another USB port if you have another one. Otherwise, insert another external storage device in this USB port.
• Step 4. Check whether the Seagate Backup Plus external hard drive is powered properly
  In general, the current of USB port 2.3 and 3.0 are enough for the most external portable hard drives. But sometimes this amount of current may be insufficient while the drive is spinning up.
• In this situation, you can try to connect the Seagate Backup Plus with a USB Y cable if you have one. And for Seagate Backup Plus Hub and Expansion Desktop, a power adaptor is required for power supply.
• Step 5. Access the drive on other Macs
  Connect the Seagate Backup Plus drive to another Mac computer to see whether it works on that one or not. If the drive works on another Mac computer, there is something wrong with your Mac computer rather than the drive. What you should do is to ask for help from Apple support.
• Step 6. Check if the format of Seagate hard drive is supported by macOS
  For example, a Windows BitLocker encrypted drive will not be working on Mac originally. Your Mac computer is not able to mount it. To fix the problem, you can plug the Seagate Backup Plus into a PC and then access the drive on Windows.

2. Check whether the Seagate Backup Plus is showing up in Disk Utility
