CrystalDiskInfo not recognizing one drive on my system

I installed CrystallDiskInfo on one of my computers. When I run it, it recognizes the system drive (C:) which is a Samsung NVMe SSD and an external drive which is a Crucial 4TB SSD. It does not recognize the original generic drive the computer came with which is a smaller 256GB SSD. The only designation I can find for it is SCA256. Windows 11 (v23H2 with April 2025 updates) recognizes it fine. I tried HWINFO and that also does not recognize it. Any ideas?

One thing I'd check is Disk Management and whether Bitlocker Encryption is shown for that drive.

How/where is the problem drive connected?

BitLocker is OFF. This is a small internal 256GB SSD drive. As I mentioned it is designated as a "Generic SCA256" drive and assigned as drive "D". The operating system was initially installed on this drive. I cloned it to a Samsung 980 Pro 2TB drive and made the Samsung the main drive. I did not reformat the D: drive. Here is the Disk Management details. One thing I noticed is that the Recovery Partition data does not seem to have been transferred from Disk 1 to Disk 0. I used Samsung Magician to do the clone and I remember some sort of issue using Samsung Magician and the Recovery Partition.
