Identifier Zero indicates that the device should check the supplied password against the user password stored internally. One indicates that the device should check the given password against the master password stored internally. The Security Erase Unit command erases all user data and disables the security mode feature (device lock function). So after completing this command, all user data will be initialized to zero with write operation. At this time it is not verified with read operation whether the sector of data is initialized correctly. In addition the defective sector information and the reassigned sector information for the device are not updated. The security erase prepare command should be completed immediately prior to the Security Erase Unit command. If the device receives a Security Erase Unit command without a prior Security Erase Prepare command, the device aborts the security erase unit command. This command disables the security mode feature (device lock function); however the master password is still stored internally within the device and may be reactivated later when a new user password is set. If you execute this command on disabling the security mode feature (device lock function), the password sent by the host is NOT compared with the password stored in the device for either the Master Password or the User Password. The device then erases all user data. The execution time of this command is set in word 89 of Identify device information. Deskstar 120GXP hard disk drive specifications 145

Identifier
Zero indicates that the device should check the supplied password against the
user password stored internally. One indicates that the device should check the
given password against the master password stored internally.
The Security Erase Unit command erases all user data and disables the security mode feature (device
lock function). So after completing this command, all user data will be initialized to zero with write
operation.
At this time it is not verified with read operation whether the sector of data is initialized
correctly. In addition the defective sector information and the reassigned sector information for the device
are not updated. The security erase prepare command should be completed immediately prior to the
Security Erase Unit command. If the device receives a Security Erase Unit command without a prior
Security Erase Prepare command, the device aborts the security erase unit command.
This command disables the security mode feature (device lock function); however the master password is
still stored internally within the device and may be reactivated later when a new user password is set. If
you execute this command on disabling the security mode feature (device lock function), the password
sent by the host is NOT compared with the password stored in the device for either the Master Password
or the User Password.
The device then erases all user data.
The execution time of this command is set in word 89 of Identify device information.
