I just added a 2TB NVMe M.2 drive to my existing setup in Windows 11, and I'm looking to have it function as another NTFS partition. After installing it in my desktop, I checked the BIOS and set my existing SSD with Windows 11 as the master boot partition. The system boots up fine, and I can see the new drive in Device Manager, but it doesn't show an active NTFS volume, so I can't access any data on it. I was surprised to find it missing in Disk Management, even after trying both "Refresh" and "Rescan Disks." I've included pictures of what I see in Device Manager and Disk Management. Any suggestions on locating and activating this drive?

You might want to try using the Command Prompt to see if the drive appears in diskpart. Just open cmd and run the commands:
1. Type `diskpart` and hit enter.
2. Then type `list disk` to see if your NVMe drive shows up in the list. If it’s there, check if it has a GPT marker next to it.

I tried that and unfortunately, it didn’t show up in the list at all.
