Windows 10 does not recognize my second hard drive

I upgraded from Windows 8.1 to Windows 10. The upgrade was very smooth except that W10 does not recognize my 2nd hard drive (no issues with W8.1). The drive is recognized in BIOS but does not show at all in W10 Disk Management. I've read other discussions that the drive may show in DM and the fix is to simply change the drive letter, but DM only shows my primary drive as Disk 0 then my USB drives. No 2nd hard drive.

I've also started in Safe Mode but have the same issue, no 2nd hard drive.

Is there a fix available? Or perhaps is it possible a service is not running which needs to be turned on?

Any help is appreciated as I need to be able to access the data and documents on the 2nd drive.

I had this problem on my laptop but not on my desktop. Windows 8.1 recognised the second drive on the laptop but 10 didn't.

Brief solution - the "best" drivers for the AHCI controller in my laptop were the Microsoft ones & update driver did not suggest a better. I manually installed the vendor's drivers (AMD in my case) and after a reboot the drive was recognised & functions fine. Hope this helps anyone else.

The MS drivers for the desktop obviously worked fine - the desktop hardware is new, though, whereas the laptop is five years old.

This minor inconvenience apart, though, I'm enjoying Windows 10 so far.
