has been overwritten and the machine has been rebooted using the [Off] - [On] procedure.
• If you specify both erase-by-overwrite and encryption, and select [Random Numbers] and set the
number of overwrites to "3", the entire overwrite and reboot process will take seven hours for the Type
3 / 4, or three and a half hours for the Type 1 / 2.
