Data Overwrite
Method
The method used to overwrite data can be changed.
Refer to the following for details.
Data Security Kit (E) Operation Guide
Value
Once Overwrite: This function overwrites unneeded data areas (in the case of
overwriting) or all areas (in the case of system initialization) with zeroes to
prevent data restoration.
3-time Overwrite (DoD): This overwrite method complies with U.S. Department
of Defense (DoD) standards, and overwrites unneeded data areas of the hard
disk (in the case of overwriting) or all areas (in the case of system initialization)
with specific characters, their complements, and random characters to prevent
data restoration. Data restoration is not possible even when sophisticated
restoration techniques are used, and a higher level of security than Once
Overwrite is obtained.
This method may take more time than Once Overwrite method to process a larger
amount of data.
Security Password Customize the security password so that only the administrator can use the security
kit.
Enter a new security password 6 to 16 alphanumeric characters and symbols.
Enter the password again for confirmation.
Avoid any easy-to-guess numbers for the security password (e.g. 11111111 or
12345678).
System Initialization 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 the power switch off during initialization, turn the power switch
on again. Initialization automatically restarts.
