Setting HDD Property
Purpose:
The HDD property can be set to redundancy, read-
only or read/write (R/W). Before setting the HDD 
property, please set the storage mode to Group 
(refer to steps 1-4 of Chapter Setting HDD Groups 
). 
A HDD can be set to read-only to prevent 
important recorded les from being overwritten 
when the HDD becomes full in overwrite recording 
mode.
When the HDD property is set to redundancy, the 
video can be recorded both onto the redundancy 
HDD and the R/W HDD simultaneously so as to 
ensure that reliability of video data is highly secured 
and realiable.

1.  Enter the HDD Information interface. 
Menu > HDD> General
