The controller firmware supports reverting an SED state to the factory default with the help of Physical Security Identifier (PSID). The PSID, or Physical SID of the drive, is a 32-character password assigned by the drive manufacturer during production. A host system cannot change the password. The PSID is on the drive label in a readable format, and depending on the drive manufacturer, it may also be available in a bar code format. If a drive is in the locked state and the key is not known then a cryptographic erase with PSID is required. The SED physical security ID (PSID) is required for reverting an SED to the non-secured factory state. For enhanced security, the PSID is accessible only by removing the drive and examining the drive label. In addition to reverting the drive state to factory default serttings, it also secure erases all existing data.
