    21.7 Ports The ports capability is an HGST feature which is not a requirement under TCG Enterprise SSC. In order to use the ports capa- bilities on encryption drives, the user must successfully authenticate. Once a user successfully authenticates, they may change the state of any of the ports at any time during an active session to either the locked or unlocked state.

    Diagnostics This port has 2 valid states: locked and unlocked. This port allows HGST access to modify any TCG table or key. In order to open this port both the SID and the Maker authorities need to be authenticated.
