I have a new Dell desktop that came with a WD 512 GB SDD, on SATA1, and WD Dashboard. The SSD shows up fine on the Dashboard. I added a WD Blue 10EZEX-08WN4A0 Blue HDD, internally, to SATA0. I cloned the OEM SDD to this Blue HDD.
The HDD shows up in Disk Management and File Explorer, but not on the Dashboard.

Yes, I have. I see my case right above your question “Have you opened a Support Case”?
I don’t understand why you are even asking. My case is right there.
