4. Preventing Leakage of Information from Machines
Using Auto Erase Memory
• When Auto Erase Memory is set to [On], temporary data that remained on the hard disk when
Auto Erase Memory was set to [Off] might not be overwritten.
• If the main power switch is turned off before Auto Erase Memory is completed, overwriting will stop
and data will be left on the hard disk.
• Do not stop the overwrite mid-process. Doing so will damage the hard disk.
• Should the main power switch be 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.
