Using Auto Erase Memory

Important

  • 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.

  • 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.
