Question Dual NVMe drives, only one showing in Windows

[Molon_Labe_1986]

I have Windows 10 installed on my Patriot 128GB NVMe drive, and a Crucial P1 1TB also. BIOS shows both drives, but my 1TB drive will not show in Windows.

Windows was installed before the 1TB drive was installed into the MB.

Crucial Storage Executive detects both drives, but Windows does not...

Any ideas??

Does it appear in Disk Management?

What motherboard is this on?

Yes, it is showing in Disk Management, as
Disk 0
Basic

with 931.50 GB Unallocated


This is on a Gigabyte Z390 Aorus Master

Had to allocate and map the drive. It's showing now. Thanks for your help!

Yep...Unallocated is often the issue.
