I have a new build with an Asus X570-E board and a MP600 1TB that I just can't get either the BIOS or Windows installer to see - both think the only drive I have is the Samsung 850 EVO SATA SSD. I've tried a series of debugging steps but the result every time is the same. So far I've tried:
Both M.2 slots
With and without the MB heat sink
Upgraded to the latest (1405) BIOS
Enabling various settings with CSM on
Disabling CSM
I triple checked and the MP600 is on the QVL for this board so it "should" just work. I'm beginning to think I just got a dud drive?
