👉Method 1: Check the Cable

The problem might be with the cable. One of the main reasons why drives fail to mount is if the drive isn’t receiving enough power. Try using a different cable with the drive to see if that fixes the problem. Similarly, if you are using a USB port via a hub check that’s not what’s causing the problem. Also check that the port on your Mac isn’t the problem. Try plugging into a different port. Or if you only have the one, plug another device in and see if that works ok.

👉Method 2: Edit the Finder Preferences

Hopefully there is a really easy fix to get the hard drive to mount on your desktop. Try the following to make sure your Mac is set to show mounted drives on the desktop:
Step 1: Open the Finder and click on Finder in the menu at the top of your screen.
Step 2: Choose Preferences - General and make sure that there is a tick beside External Drives.
If it was already set up so that the external drive would appear on the desktop.

Step 3: Now wait for the repairing to be completed! That’s it! Now let’s move to last solution.

👉Method 5: Change the Drive Format

Step 1: Open Disk Utility as previously we did.
Step 2: If you don’t require the data on the hard drive, select the disk and click Erase.
Step 3: Before Disk Utility starts to erase the disk it will pick a format for you. You can change this if you click on the Formatting options.
