Second internal hard drive is recognized but not accessible

I have a second internal hard drive installed in my system that I use as storage for audio and video files. Since upgrading to Windows 10 I have not been able to access this drive. It is recognized, but not accessible by any means that I am familiar
with. It is a healthy collection and it would be disturbing to lose this data, so I have not made any attempts outside of my comfort zone. Recommendations would be very helpful.

 

Windows no longer recognizes second internal hard drive

Why is it both Windows 8.1 and Windows 10 no longer recognize a second internal hard drive?

Previously in both my Windows 8.1 and Windows 10 PC’s, I had an internal second drive connected in each PC and both worked quite well. In the case of the Windows 8.1 PC, I used to use the second internal drive to do system image backups and the second
internal hard drive in the Windows 10 PC as a File History drive.

But now, in both PC’s, the internal second drives are no longer being recognized. Both File History and System Image backup now only work when drives are connected externally.

If the second hard drives are connected internally, this error message comes up : "Operating system not found" on the Windows 8.1 PC and "no usable hard drives found" for File History on the Windows 10 PC.

Surely that should not be the case? What could be the cause?
