Password protection for the hard disk
If a supervisor password was set, an additional password for the hard disk
can be set in the Hard Disk Security menu.
The hard disk is protected by this password. Data on this hard disk can then only be
read in another system if the correct password is entered.
Trusted Platform Module - TPM (device dependent)
