Overwrite Temporary Data

You can specify how to overwrite and delete HDD data.
When image data saved in the HDD becomes unnecessary, this function overwrites meaningless data in all
areas that contain the image data to destroy the original data. This function also destroys the non-image data
structure to prevent a data leak when the installed HDD has been stolen.
The available setting items are as follows. (Default: Mode 1)
Item
Mode 1
Mode 2
Encryption Priority
Overwrite Priority
Reference
- When changing Encryption Priority or Overwrite Priority setting, format the HDD after rebooting this
machine. However, be careful that data is erased by formatting the HDD.
- For the data erased by formatting the HDD, refer to page 8-30.
