Make sure you don't have it as a raid device or part of a raid setup. That sometimes hide drives.
Make sure your BIOS is up-to-date and also make sure Windows is at the latest build (1903). I presume you are running Windows 10, yeah?
Also previous reply also mentioned, if you have them in a RAID 1 or RAID 0 per say, you will only see one disk in Windows.
