External Hard Drive Not Showing Up in Finder

I use my computer today and notice the external HD is not on my desktop. It is running, but not displaying on the desktop. My first step is to restart the computer. I restart the computer and still nothing and I opened up disk utility. The hard drive shows up in the disk utility. I have run both First aid to the external HD and after the scans it says the HD appears to be OK. I restart the computer and nothing happens. I can also eject the HD from the disk utility. After it is ejected I can unplug it and plug it back in and it will display in the Disk Utility, but nowhere else. It does not show up on the desktop and does not show up in the side bar. I have also gone into to preferences to verify that the box is checked to show the external HD.
I am trying to give as much detail as I can to help diagnose the problem and I have searched through the forums but can't seem to find anything or anyone that has had a similar problem. I need pointed in the right direction to try and figure out why the HD is not showing up on the Desktop.

Any help or suggestions would be greatly appreciated.
