Drive not showing in Windows

[cubewhiz]

Hey all,

I just built a new PC. The motherboard is the Asus Z170-AR. The drives are as follows:

Samsung 950 PRO M.2 drive.
WD 7200 RPM 1TB HDD (installed in SATA port 3)
Asus OD (installed in SATA port 6)

The problem is that all drives are recognized in BIOS, but in Windows, I only see the SSD and OD. How can I access the HDD?

Thanks!

So you have the OS installed on the SSD?
And you've connected the HDD, but it does not appear in Windows Explorer?
And this is a brand new HDD?

If so...
Open Disk Management.
Does it appear there?
If no, it is broken or disconnected.
If yes, then it just needs to be initialized.
Right click on that drive, Initialize, and follow whatever else it tells you to do.
