I recently enabled Optane to accelerate a secondary 1TB drive. It was working fine for a few weeks but now Windows no longer sees the drive. It previously was "E:". Disk Management does not see it. When I go into the BIOS I can see the 1TB drive in the storage settings. How can I get Windows to see the 1TB drive again?
Thanks for the help. I can see in the BIOS that the 1TB drive is connected to SATA 5. And I do have a firewire card installed in the PCIe x16_3 slot. The fireware card was installed after I setup the Optane acceleration. Perhaps the firewire card is somehow interfering?
I will try moving the card to another slot.
Although I'm still not sure what caused the accelerated drive to "disappear," I have it back working again. You can close the case. Thanks for the help.
Sharing the solution in case someone else runs into the same problem ...
The solution was to temporarily set BIOS to AHCI and boot to a Win PE partitioning tool CD. The partitioning tool was able to see the drive and that there was a deleted partition and recover it. I set the BIOS to RST again and Windows booted normally and the drive is accessible again.
I have yet to reconfigure the Optane memory to accelerate the drive, but will do that next.
