Using Auto Erase Memory
When the optional hard disk is installed and Auto Erase Memory is set to [On], temporary data that remained on the hard disk while Auto Erase Memory was set to [Off] might not be overwritten.
When the optional hard disk is installed, overwriting will stop and data will be left on the hard disk if the main power switch is turned off before Auto Erase Memory is completed.
Do not stop the overwrite mid-process. Doing so will damage the hard disk.
If the main power switch is turned off before Auto Erase Memory is completed, overwriting will continue once the main power switch is turned back on.
If an error occurs before overwriting is completed, turn off the main power. Turn it on, and then repeat from Step 1.
The machine will not enter Sleep mode until overwriting has been completed.
