When an administrator password is set, you are prompted to enter a valid password each time you
try to access the Setup Utility program. The Setup Utility program cannot be accessed until a valid
password is entered.
If both the power-on password and administrator password are set, you can enter either password.
However, you must use your administrator password to change any configuration settings.
• Hard disk password
Setting a hard disk password prevents unauthorized access to the data on the storage drive. When a
hard disk password is set, you are prompted to enter a valid password each time you try to access
the storage drive.
Notes:
– After you set a hard disk password, your data on the storage drive is protected even if the storage drive
is removed from one computer and installed in another.
– If the hard disk password is forgotten, there is no way to reset the password or recover data from
the storage drive.
Password considerations
A password can be any combination of up to 64 alphabetic and numeric characters. For security reasons, it
is recommended to use a strong password that cannot be easily compromised.
Note: The Setup Utility program passwords are not case sensitive.
To set a strong password, consider the following guidelines:
• Have at least eight characters in length
• Contain at least one alphabetic character and one numeric character
• Not be your name or your user name
• Not be a common word or a common name
