Welcome to the community, helloleigham!

I'd recommend you to go to Disk Management and check if your secondary HDD is recognized there. If it's a brand-new one, it would be listed as Not Initialized/ Unallocated (Black bar). Here's a link that explains how to get to Disk Management: http://www.isunshare.com/windows-10/7-ways-to-open-disk-management-in-windows-10.html

Afterwards, you can simply right-click on the volume of your secondary drive and allocate the space by initializing the drive and then partitioning & formatting it. Here are a couple of more tutorials that can help you out with that as well:

After these procedures are finished, you should be able to access through Windows Explorer (This PC).
P.S. If you have data on the drive, these procedures will erase everything on it, make sure you do a backup somewhere else beforehand.

Hope I helped!
