The SECURITY DISABLE PASSWORD command requests a transfer of a single sector of data from the
host. The following table defines the content of this sector of information. Then the device checks the
transferred password. If the User password or the Master password match, the device disables the lock
function. This command does not change the Master password that may be reactivated later by setting a
User password.
