Description

Drive is Opal*-encrypted and there is no way to access the data.

Note

This process will erase your password and all data in the drive.
This process is applicable only to Intel® Optane™ SSDs compatible with Opal encryption. For a complete list of drives, refer to Intel® Optane™ SSDs with TCG Opal 2.0* Support.
The process of reverting the Opal encryption is done through the Intel® Memory and Storage Tool (CLI).
The process may fail if the drive has partitions. To avoid this error, it's recommended that you delete all partitions beforehand. To learn some options to perform this action, refer to When to Run a Low-Level Format or Secure Erase on Intel® Optane™ SSDs and Tools to Use.

Follow these steps to revert the Opal encryption in your Intel® Optane™ SSD:

Download the Intel® Memory and Storage Tool (CLI).
Connect your Intel® Optane™ SSD directly to your motherboard.
Start the Intel® Memory and Storage Tool and run the command: intelmas start -intelssd <drive_index> -psidrevert <PSID>
- <drive_index> corresponds to the index assigned to your drive. You can easily identify your drive by running the command: intelmas show -intelssd
- <PSID> corresponds to the PSID (Physical Security ID) printed on the drive's label.
After the process is complete, the drive will be reverted to its factory settings, previous password will be deleted and all data will be erased.
