Issue

• I. Create a bootable OPAL recovery USB device
• II. Boot the USB device on the workstation and perform a PSID (Physical Security ID) revert to completely erase or unlock your OPAL encrypted disk

Details

PSID revert is the process of erasing a locked OPAL specification disk and unlocking the drive. You may need to perform a PSID revert if your OPAL disk is currently locked. PSID is a unique 32-character alphanumeric identifier for OPAL disks. The PSID is normally printed on the disk label. 

Solution

To perform a PSID revert, you need a blank USB flash drive formatted as FAT32. Ensure that you back up any data stored on the USB flash drive before formatting, as this will erase all data on the USB flash drive.
