Hard Disk Passwords Two types of the hard disk passwords help protect the information stored on the hard disk: · Hard disk user password · Hard disk master password, which requires a hard disk user password If a hard disk user password has been set, but no hard disk master password has been set, the user must enter the hard disk user password in order to gain access to files and applications on the hard disk. The master password can be set and used only by a system administrator. Like a master key, it enables the administrator to get access to any hard disk drive in a system. Then the administrator sets a user password for each computer in the network, and tells each user the password for his or her computer. The user can then change the user password as desired, but the administrator can still get access by using the master password. To set a hard disk password: Print these instructions. 1 Turn on your computer. Press F2, while the initial screen is displayed.
