How to fix external hard drive not mounting in macOS Catalina/Mojave issue?
Solution 1: Check if the hard drive is properly plugged in.
Since the connection between your Mac and external hard drives relies on cables, loose connections could be the cause that your external hard drive is not recognized by your Mac computer.
If the unstable connection is the case, your external hard drive would not be mounted even with a slight disturbance. Sometimes the cable itself will become hot because of a faulty connection. Therefore, you need to make sure that the connection, i.e. the USB cable, is in good condition.
Solution 2: Check if the USB port/USB hub is unmatchable, damaged or lack of power.
If your external hard drive or USB flash drive is not mounted on Mac, try plugging it into another USB port or a USB hub. That's because there're USB 3.0 and USB 2.0 ports and they have some differences: USB 3.0 has higher transfer rates, provides more power, more bandwidth, etc. than USB 2.0. As you can see, insufficient power supply or damaged USB ports could also lead to external hard drives not mounting in macOS Catalina/Mojave/High Sierra.
To check this error, you can unplug the problematic external hard drive and plug a functional external hard drive into this USB port to see if it can be mounted normally.
Solution 3: Check if your Mac is set to show mounted drives on the desktop.
It's also possible that your Mac has alreadyrecognized the external hard drive butnot showing up on Mac desktop or Finder. Under such circumstance, you should go to Finder > Preferences > General and make sure the 'External disks' option is ticked. Then you'll see the external hard drive mounted on the desktop.
You can also set your Mac to show external hard drives in Finder. Go to Finder > Preferences > Sidebar and make sure the 'External disks' option under 'Locations' is ticked.
Solution 4: Check if the external hard drive is NTFS formatted.
NTFS (New Technology File System) is a proprietary file system developed by Microsoft. However, for some reasons, macOS comes with read-only support for NTFS; its disabled-by-default write support for NTFS is unstable. Even though the NTFS formatted external hard drive can show up in Disk Utility, external hard drives might not be mounting as normal.
You can go to Disk Utility and check the file system of the external hard drive is NTFS or not, if this is the case, you can back up the files on the NTFS external hard drive and format it to Mac supported file systems (APFS, HFS+ or HFS) or file systems supported by both Windows and Mac, like FAT32 and exFAT.
Nevertheless, the best phenomenon is that you can read and write NTFS both on Macs and on Windows without fuss. So, a good NTFS for Mac application will enable you to write NTFS external hard drives on macOS without reformatting.
