Windows 10: Second hard drive no longer being identified by Windows 10

I have a second hard drive connected internally as my File History drive on my Windows 10 PC. All along it had worked fine but now I find that it is no longer being identified by Windows 10 at all. It does not appear in File Explorer and not even in Disk Management or BIOS. I have changed the cable but to no avail. What could be the problem and what do I need to do to get the drive working again? Can someone please advise.

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?
