Ok, go easy on me. I have moved away from desktop support to application support years ago. My last computer purchased was 9 years ago, and I decided it was time to buy a new one. I purchased the PO3-630 with a 512gb NVMe and a 1TB 3.5 SATA drive installed. I have removed the 1tb SATA drive, and replaced it with a WD Red Plus 10th drive. Booting in to Windows, I don't see the drive in Disk Management. I rescan the disks, still not detected. I go in the BIOS, but I don't really see any options that would make the board see the drive. Inside Windows, the WD utility sees the drive, as seen in my attachment. What am I missing, likely in the BIOS I am guessing, that is keeping my drive from being detected?
