(6) HDD securely erasing (Erase HDD Securely)
This function is used before discarding the HDD.
It overwrites all the used areas on the HDD with the selected data, and makes it unusable.
After selecting this function, specify the level below to be overwritten.This setting is the
overwriting method complying with DoD 5220.22-M.
1. LOW
This is the standard overwriting method.
"00-FF-Random-Verify" Once
2. MEDIUM
This overwriting method is more secure than LOW. The erasing time is between LOW and
HIGH.
"00-FF-Random" three times repeatedly -Verify
3. HIGH
This is the most secure overwriting method. It takes the longest time to erase data.
"00-FF-Random" five times repeatedly -Verify
4. SIMPLE
This is the simple overwriting method. It takes the shortest time to erase data.
Overwrite the Random data once
Key in the level number to display “<“ next to it.
(At this time, if “0” is entered, the screen returns to the initial one of the Assist Mode.)

button again to start overwriting.

When this operation has been done, do not perform SRAM data formatting (Clear SRAM) before
the normal start-up.
(7) SRAM securely erasing (Erase SRAM Securely)
This function is used before discarding the SRAM board (for the SYS board).
It overwrites all the used areas on the SRAM board with the selected data, and makes it
unusable.
Immediately after selecting this function, the processing starts and is completed.
(8) SRAM service tech password formatting (Clear Service Tech Password)
This function is needed after the HDD is replaced.
When the HDD is replaced, the service tech password stored in the new one is set as a blank.
Therefore, its password is copied to the SRAM board so that both passwords become the same
with this function.
