5.  Set HDD Status to Read-only and then click OK to finish the setting.   
 
Note:
 When a HDD is set to read-only, no more recordings can be written to the disk. In order to enable recordings 
on that particular disk again, you must set the HDD to R/W (Read/ Write) in the HDD Property Settings menu. If 
multiple HDDs are used, the DVR will automatically record to the next HDD that is not set to read-only.
