Most of us probably use only one hard disk drive in the computer, but some people who need more space, tend to use two, as well. And some of the users who are using the second hard drive have reported that their computer isn’t able to detect the second one, after Windows 10 upgrade. So we came up with a couple of solutions, which, I hope, will solve the problem.

First thing first, you should open your computer once again, and check if your hard disk is properly connected. If you’re not sure what to do, check out this article for additional info. If everything is connected right, but you’re still facing the issue with detecting your second hard disk drive, try one of the following solutions.
