Hello!
I have a Samsung 970 Evo Plus installed in the PM1 slot of the x299 Dark and it is not being detected properly.
A GPU is in PE1.
A Samsung 970 Evo is in PM2 and is detected just fine.
All other PCIE and SATA ports are unoccupied and I have made sure PM1 is enabled in BIOS.
What is strange is the Evo Plus in the PM1 slot will only show sometimes in BIOS and Disk Management and does not show at all in diskpart. When it does show up in Disk Management, I attempt to initialize it and I get an "Incorrect Function" error. Due to the erratic behavior, I'm suspecting the Evo Plus is a bad drive? Or am I missing something here?
