You could just set the option 'Erase video after (days) " to not fill up the drive. It's under Recording configuration-> Record Quality-> 'Record' tab. Make sure you set the appropriate camera you want video deleted on.

You can try this (I'm trying it too): Set the system date/time in the System Configuration screen to be the day that you want to delete. Then from the main menu select Recording configuration and choose the Record Quality option. Then select the 'Record' tab. Select the camera you want to delete video on. In the field marked 'Erase video after (Days)" type '1'. Wait a day and see if that days video is erased without erasing the other days. For instance to erase Feb. 3, 2016, set the system data to Feb.3, 2016. On Feb. 4th the Feb 3rd video should be deleted. I don't know if this will work but It seems logical. I'm going to try and see what happens.
