This command disables the security mode feature (device lock function), however the master
password is still stored internally within the device and may be re-activated 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
both the Master Password and the User Password, and then the device only erases all user data.
The execution time of this command in Normal Erase mode is shown below.
