Data to be protected
Use the Enhanced Security mode to prevent the data from being written to illicitly-switched HDD.
Also, the following data managed by the administrator is better secured:
User data
Data to manage the machine
Data not to be protected in Enhanced Security mode
When the machine is connected to a computer via a local network, the password you entered on a computer is not subject to the Enhanced Security mode. Avoid entering any password from such PCs for prevention of leakage.
