How to Clean Intel® Optane™ Memory Using Diskpart


Windows® 10, 64-bit*


Steps to clean the data in Intel® Optane™ memory using the Diskpart utility.


If Intel® Optane™ memory has partitions, or in general if for any reason it has any data stored (such as metadata from a previous configuration), the process to enable it may fail. In those scenarios, it is recommended to clean the module's data.

NoteThis process may cause data issues. Back up your data before following these steps.

Follow the below steps to clean the module's data using Diskpart:

  1. Open the Command Prompt as Administrator.
  2. Run the command diskpart
    • You'll enter into the Diskpart environment.
  3. Run the command list disk
    • This command will list all the storage drives currently connected and recognized in your system. If Intel® Optane™ memory is properly installed and not enabled yet, you'll see it here as well.
  4. Run the command select disk <index_number>
    • Use the index number associated to the module. For example select disk 2
  5. Run the command clean all to start the cleaning process.
    • Make sure you have selected Intel® Optane™ memory and not another drive by mistake because this process will delete all data in the disk.
  6. Once the process is complete, confirm in Disk Management that the module's space is unallocated.
