I use INTEL OPTANE 32 Gb memory to accelerate my data disk - a Western Digital 2gb drive. Installation of the OPTANE was relatively easy and everything worked well. I wanted to back up the data disk with Macrium Reflect software and I was not sure if the data disk backup image can be properly done with the OPTANE memory enabled. So I used the INTEL OPTANE memory application to disable the OPTANE memory. The disable process started (the rotating dots) and showed "step 1 or 3" etc. Eventually, the disabling process got stuck on "step 3". After about 1 hour of the "step 3", I decided not to wait any longer and restarted the computer. The data disk no longer appears in the File Explorer and the Disk Management shows only the OPTANE memory as 7,2 Gb "unallocated" and requiring initialization as GPT. I went into BIOS, Advanced mode and disabled the OPTANE memory in BIOS. As a result, the Disk Management now again shows my data disk as 2 Tb, but "unallocated", and separately shows the OPTANE memory as 32 Gb.
So, as a final result, my attempt to disable the OPTANE memory ended up in wiping out all data on my data disk.
Can you give me any idea of what went wrong and how I can restore my data disk and what am I supposed to do next time if I need to properly disable OPTANE memory?
My system uses ASUS ROG STRIX Z370-E motherboard, INTEL i7-8700K CPU, Samsung 970 PRO M.2 NVME SSD as a boot disk and a Western Digital 2 Tb drive as a data disk, formatted as a GPT disk.
A day later: Many thanks to Al Hill for researching this and giving valuable answers!
After unsuccessfully trying to disable OPTANE memory and then disabling it in BIOS, the Disk Management as well as my Paragon Partition Manager both showed the data disk as "2 Tb, Unallocated". Strangely enough, though, the Macrium Reflect showed the data disk as normal, active and with data. With an increasing hope, I used Macrium to create a backup image of the Data disk and after about 1 1/2 hour when it finished, I could explore the image and saw that all data was there and in perfect shape. So I restored the image back to the Data disk. As Macrium did not discover any changes, the restore took only about 1 minute and now my Data disk was again on line and functioning perfectly. Hooray for Macrium Reflect!
At this point, I am thinking of re-enabling the OPTANE memory.
In respose to Al Hill's last message, about the scenario 3 - when HDD paired with OPTANE memory is backed up with the OPTANE enabled and then it fails - I think that in that case, as a last resort, one could right click on the existing image and use the "Explore" option available in Macrium Reflect and simply copy all needed files to the new HDD. This would not work for a boot disk, but probably would work OK for a Data disk.
I still have a general question - how long is disabling of the OPTANE memory supposed to take? In my case, I waited 1 1/2 hour before I gave up and rebooted the computer. The INTEL instruction video on disabling OPTANE memory makes it look like it should take only a few seconds (and Al Hil'sl description is similar). The video also shows that during the disabling process, a number showing percent finished should show inside the rotating circle of dots. In my case, it did not show...
