Figure 104. Security Set Password Information
Identifier
Zero indicates that device regards Password as User Password.
One indicates that
device regards Password as Master Password.
Security Level
Zero indicates High level, one indicates Maximum level. If the host sets High level
and the password is forgotten, then the Master Password can be used to unlock the
device. If the host sets Maximum level and the user password is forgotten, only an
Security Erase Prepare/Security Unit command can unlock the device and all data
will be lost.
Password
The text of the password - all 32 bytes are always significant.
The setting of the Identifier and Security level bits interact as follows.
Identifier=User / Security level = High The password supplied with the command will be saved as the new
user password. The security mode feature (lock function) will be enabled from the next power
on. The file may then be unlocked by either the user password or the previously set master pass-
word.
Identifier=Master / Security level = High This combination will set a master password but will N O T
enable the security mode feature (lock function).
Identifier=User / Security level = Maximum The password supplied with the command will be saved as the
new user password. The security mode feature (lock function) will be enabled from the next
power on. The file may then be unlocked by only the user password. The master password pre-
viously set is still stored in the file but may N O T be used to unlock the device.
Identifier=Master / Security level = Maximum This combination will set a master password but will N O T
enable the security mode feature (lock function).
