[NAME]​ You cannot find it in Device Manager? It may not show up under Disk drives if it is not yet initialized or if it is initialized as MBR. Look for UNKNOWN or some such thing.
I installed a WD_black M.2 SSD on the motherboard, but it is not recognized. I've never used one before. From what I'm reading on various tech blogs and community sites, it looks like often the advice is to set the BIOS SATA mode to IDE. But the Alienware BIOS (which is UEFI) does not have an "IDE" option. The options are "RAID" (the default) and "ACHI". On top of that, I see the warning that if I choose ACHI, my original drive will become unbootable.  It looks like the only way to use the M.2 is to choose ACHI. And that in turn requires a complete reinstall of Windows. But before I go down that road, I want to know if anyone has done this, and knows if I am on the right track?
