Please see: Intel Optane    You basically have to go into the Intel RST drivers menu and select the drive you wish Optane to work with.
Hi Everyone, I'm needing to replace the harddrive on an Area51 R4.  The current drive is a 1TB, and there is 32 GB of Optane Memory.  The current HDD is starting to click, so I put another drive in (750GB) as a temporary fix until deciding whether to install an SSD or stick with a standard spinning drive.  I could go with an NVME and remove the Optane memory too. When the 1TB drive is installed, in Device manager, under Drives, it's listed as INTEL OPTANE + 932GBHDD. When I installed the 750GB and loaded all drives, it's only showing the 750GB drive.  There is no mention of the Optane drive in Device manager. I went into the BIOS, but didn't see anything that specifically mentions Optane.  There are some Intel settings, but they're all enabled. Has anyone else run into this issue?  I would ideally like to have the Optane memory running with the 750GB drive at least temporarily until obtaining and instaling a replacement.  I'm wondering if the 750GB HDD is incompatible, or if there is an additional driver/setting (outside the drivers on Dell's site) that I would need to get it to show for any harddrive I install. Thanks!
Area-51 R4, Optane Memory not showing with replacement HDD
