Item Description
SSD Initialization
Hard Disk Initialization
This changes security function settings.
• This function is displayed when the optional hard disk/SSD is installed and the Data
Encryption/Overwrite is activated.
• Display changes according to the large storage capacity installed on this machine.
When an SSD is installed: SSD Initialization
When a hard disk is installed: Hard Disk Initialization
• Input of the security password is required to change security function settings. The initial
setting for the Security Password is "000000".
Data Overwrite
Method
*1
*1 This function is displayed when the hard disk is installed.
The method used to overwrite data can be changed.
Refer to the following for details.
Data Encryption/Overwrite Operation Guide
Value
Once Overwrite: The 1-time overwrite method overwrites unneeded data areas
(in the case of overwriting) or all the data areas (in the case of system
initialization) with specific numbers to prevent data restoration.
3-time Overwrite (A): The 3-time overwrite method complies with DoD 5220.22-
M, and overwrites unneeded data areas (in the case of overwriting) or all the
data areas (in the case of system initialization) with specific numbers, their
complements, and random numbers to prevent data restoration. Data
restoration is not possible even through a sophisticated restoration technique.
This method may take more time than Once Overwrite method to process a larger
amount of data.
Security Password You can customize the security password so that only the administrator can use the security kit.
Enter a password that uses 6 to 16 alphanumeric characters and symbols.
You will need to enter the password again for confirmation.
Avoid any easy-to-guess numbers for the security password (e.g. 11111111 or 12345678).
System Initialization This can be used to delete all the data stored in the hard disk/SSD. Overwrite all the data
stored in the hard disk/SSD when disposing of the machine.
If you accidentally turn the power switch off during initialization, the hard disk/SSD
might possibly crash or initialization might fail.
If you accidentally turn off power during initialization, turn it back on. Initialization will restart
automatically.
