Q: Seagate External Hard Drive

Since upgrading to Sierra, my Macbook will not recognize when my Seagate 4TB External Hard Drive is connected (no issues prior to the upgrade).  Another issue is that when I click the Finder icon in the tray, a finder window pops up, then the whole screen goes black momentarily, then comes back up with all icons, but the finder window is now gone.

MacBook, macOS Sierra (10.12), Retina, 13-Inch, Mid 2014
