Adding second drive to MSI Raider 18 HX AI A2XWJG-416US 18

Have a new MSI Raider 18 HX AI A2XWJG-416US 18 and wanted to add a second drive since this rig will be for 3D scanning and processing meshes and CAD work. I purchased a 4TB samsung NVMe drive (Samsung - 990 PRO 4TB Internal SSD PCle Gen 4x4 NVMe) and when I booted up after the install I could se the drive in windows 11 Pro disk manager. I created the partition and formatted it, and thought nothing of it. After about a week I booted up and started installing my scanning software and CAD tools, and D drive is no longer there and not showing up in disk manager. It's a total pain in the ASS to crack this thing open but it looks like I'll have to. I also looked in the bios and its not showing up there either.
