  • You need to perform a PSID revert on an OPAL disk 


Click to expand

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.


Performing a PSID revert

PSID revert process will erase all data on the disk and is irreversible. If Windows is accessible, ensure you back up all important data from the disk before performing a PSID revert.

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.
