Because of the way that Optane(TM) Memory works, once you have enabled it it will become hidden in both your OS and BIOS. It's common for Optane™ Memory to remain this way even after you've reinstalled Windows or swapped boot drives.
Here's what you'll need to do in order to recover your Optane(TM) Memory module:
1. Open an Administrator Command Prompt (Right click on your start menu icon, select "Command Prompt (Admin)" from the list).
2. Type "diskpart" and press enter
3. Type "list disk" to display a list of your connected storage devices. Here you should be able to see your memory module, note the disk number.
4. Type "Select Disk 1" and press enter. Make sure to adjust to match the disk number displayed for your module. For this example we used a 16GB module.
5. Type "Clean all" and press enter. Diskpart will proceed to low-level format your memory module, this process may take several minutes. You will not see a progress bar, but a blinking cursor. Once the command completes you may close command prompt.
Alternatively, you may reset your Optane(TM) module from within your BIOS. Keep in mind that these settings will vary depending on your motherboard brand and model, you may need to contact your hardware vendor or review your manual if the settings we provide are not a match for your system:
1. Open your UEFI BIOS Utility.
2. Switch to "Advanced Mode" by pressing the F7 key.
3. Go to the "Advanced" tab.
4. Scroll down to "Intel(R) Rapid Storage Technology" and enter.
5. Select your Optane(TM) module. May display as something along the lines of "PCIe 1.0, Intel MEMPEK1W0......", enter.
6. Under "Disk Actions:" there should be an option to "Reset to non-Optane." This option will reset your module and allow you to detect and enable it again.
Once you have followed these steps, you will be able to restart your computer and enable system acceleration once again. If you have any issues along the way, or if your issue is resolved, please let us know.
Thank you for your answer.
Unfortunately, as I mentioned, both Windows and BIOS cannot detect Optane module, meaning they can only see my HDD, so that I'm not able to recover Optane. Please review attached screenshots.
I also don't think this is hardware failure, because my 2nd Optane module have this problem too.
Reinstalling your OS should by no means "break" your Optane™ memory. Since your module is not just hidden but actually not being detected our next step will be to confirm your BIOS settings:
1. Under Advanced\PCH Storage Configuration:
1. If SATA mode is set to AHCI, One Click should be enabled
2. Otherwise your SATA mode should be set to Intel® RST Premium
2. Under Advanced\Onboard Devices Configuration:
1. M.2_1 Configuration should be set to Auto or PCIe
3. Boot tab:
1. CSM should be disabled
2. Secure Boot should be set to Windows* UEFI Mode
Once these settings have been set/confirmed you should be able to reboot and see your memory module to reset in the Advanced\Intel® Rapid Storage Technology screen.
If after verifying these settings you're still unable to detect your Intel® Optane™ Memory, there will only be two options:
1. Install the module on another motherboard meeting the base hardware requirements (for the module to work as storage, not for system acceleration) which are as follows: M.2 PCIe* 3.0 x 2 lanes Slot. If this second board detects the module, you may perform the low level format procedure and test it again on your original system.
2. Contact your place of purchase (if within the initial 30 days), or our support team to initiate a warranty replacement if applicable.
We look forward to hearing back from you.
You're welcome. We're glad to hear that your issue was resolved.
