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.

Master Password

The Revision Code field is set with Master password. If Identifier is User, the Revision

Revision Code

Code is not set. The Revision Code field is returned in Identify Device word 92. The valid

 

Revision Codes are 0000h to FFFDh. Default Master Password Revision Code is FFFEh.

 

FFFFh is reserved.

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 password.

Identifier=Master / Security level = High

This combination will set a master password but will NOT 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 previously set is still stored in the file but may NOT be used to unlock the device.

Identifier=Master / Security level = Maximum

This combination will set a master password but will NOT enable the security mode feature (lock function).
