2.6 Protecting Data in the HDD
If the optional Hard Disk HD-504 and Security Kit SC-504 are mounted on
the machine and when access to the Admin. Management mode by the Ad-
ministrator of the machine is authenticated, the machine enables the opera-
tion for setting and changing the HDD Lock Password and Encryption Key.
Should the HDD be removed unawares, the HDD Lock Password locks the
HDD protecting data contained in the HDD. Furthermore, by setting the En-
cryption Key, the data stored in the HDD is encrypted, thereby protecting the
data in the HDD. The HDD Lock Password and Encryption Key entered is dis-
played as “*.”

Note
Do not set any number that can easily be guessed from birthdays, em-
ployee identification numbers, and the like for the HDD Lock Password
and Encryption Key. Try to change the password at regular intervals.
Make sure that nobody but the Administrator of the machine comes to
know the HDD Lock Password or Encryption Key.

Reminder
When the HDD Lock Password is set, HDD verification is carried out
when the machine is started. If the HDD has been improperly replaced
with another, or if the HDD Lock Password is yet to be set, a message
appears that tells that there is a mismatch between the HDD and the HDD
Lock Password. Further, the HDD has the following function. That is, if
the HDD is illegally removed, detection of a wrong HDD Lock Password
five consecutive times will lock the authentication function. Leak of data
can thus be prevented.
When an Encryption Key (encryption word) is set using HDD Encryption
Setting, an Encryption Key with a key length of 128 bits is generated us-
ing the SHA-1 algorithm. The generated encryption key is used to encrypt
or decrypt data through AES encryption algorithm.
