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

To troubleshoot this problem, you first need to know if this Seagate hard drive is detected by your Mac. Open the Utilities folder in your Applications folder. Launch Disk Utility and check the left pane then. If you can't see the external hard drive in macOS, the drive probably has been physically damaged. In that case, you should send the drive to the local repair shop. Otherwise, you can move to the next solution.

3. Check if the Seagate Backup Plus drive is mounted in Disk Utility

If the Seagate Backup Plus is mounted in Disk Utility, you should blame the wrong computer settings or outdated computer. Fortunately, it's easy to fix these issues. Just try solution 4 and solution 5. If the external hard drive is greyed out in Disk Utility, it's not mounted. You can try right-clicking the Seagate Backup Plus and choose the 'Mount' button. If that doesn't work, the drive has some file system problems. Please follow the solution 6 to repair the problem.

4. Show the Seagate Backup Plus on the desktop

If the Seagate external hard drive is mounted in Disk Utility, but it still doesn't show up on Mac. First of all, you should make sure the settings in Finder display drive icons on the desktop.

1. Go to Finder > Preferences > General tab.
2. Select 'External disks' under 'Show these items on the desktop' and then the connected external hard drive will appear on the desktop.

5. Repair Seagate Backup Plus drive via First Aid

Seagate Backup Plus not mounting issue on Mac can be caused by file system problems. Disk Utility's First Aid is a built-in tool on Mac to deal with errors related to disks, such as file system corruption. So you can try to fix the unmountable/corrupted Seagate Backup Plus external hard drive in Disk Utility by following the steps below.

3. Select the Seagate Backup Plus external hard drive from the left sidebar.
4. Click 'First Aid' on the top of the Disk Utility window.
5. Click 'Run' to perform hard disk diagnostics and fix the not mounting/not working Seagate Backup Plus.

6. Update the software on Mac

Software updates keep your computer and programs secure, deal with quite a few bugs, and provide new features. Out-of-date software can cause a variety of issues. It's possible that the operating system will become sluggish and the connected device may not function properly. Fortunately, you can easily update the software on Mac.

Case 1. Update the software on macOS Mojave or Catalina. If you upgrade to macOS Mojave or macOS Catalina, you should choose 'System Preferences' from the Apple menu, then click 'Software Update' to check for updates. If any updates are available, click 'Update Now' to install them.

Case 2. Update the software on earlier macOS versions. Just launch the Mac App Store, click the 'Update' tab on the top and then choose the 'Update All'.

7. Fix the not mounting or working Seagate Backup Plus drive by reformatting

If First Aid failed on the external hard drive, it might have some serious errors that are beyond its reparation capability. In that case, you need to recover lost data from the Seagate Backup Plus external hard drive as soon as possible.

October 1991 saw the introduction of Macs using Motorola’s high-octane 68040 CPU. The Quadra 900 was a full-fledged tower design, although it had only a single front accessible drive bay. The Quadra 700 and 900 were the first Macs with built-in ethernet, using Apple’s AAUIs connector.

Huge. It’s one of the first adjectives that comes to mind, along with monstrous, massive, and just plain big. The 303W power supply alone is about the same size as a compact Mac. The Quadra 900 is build like a tank and obviously designed to sit on the floor. With 16 SIMM slots, you can add incredible amounts of memory, along with plenty of high capacity SCSI hard drives. This is obviously designed to be used as a server.

According to Apple, the monstrous power supply can support two 25-watt NuBus cards and three of the more typical 15-watt cards.

The internal SCSI bus is terminated on the motherboard, so internal SCSI devices should not be terminated. This is the opposite of all other Macs, except for the similar Quadra 950. However, the external SCSI bus works the same as on other Macs.

Although there are two separate SCSI buses, System 7.0-7.1 “folds” them together so the operating system sees a single virtual SCSI bus. Thus, under System 7.0-7.1 (and only under those systems) you must make sure that all devices on both chains have unique IDs.

See our NuBus Video Card Guide for information on adding a video card.

The 900 was replaced by the 33 MHz Quadra 950 in May 1992.

Cautions

Outside of California, Apple discontinued support and parts orders for this model on 2001.01.01. You may be able to find dealers with parts inventory either locally or on our parts and service list.
In 24-bit video mode, the Quadra 700 and 900 actually use 32-bits per pixel. While most Macs can display 24-bit video at 640 x 480 with 1 MB of VRAM, you must have 2 MB VRAM for 24-bit on these models (see Apple Knowledge Base Archive #10992 for more details).
You must have a “fat” system installed to use a PowerPC upgrade as well as the 68040 CPU.
