Setting the HDD to read-only
When you set an HDD to read-only, recorded video files cannot be written to the
HDD. If multiple HDDs are used, the DVR automatically records to the next HDD
not set to read-only
To set a HDD to read-only:
1. Click the System Setting icon in the menu toolbar.
2. Click Hard Disk to set up the HDD parameters.
3. Select the HDD you want to set to read-only.
4. Check Read only .
5. Click Apply to save the settings. The HDD is now read-only.
Note: In order to enable recordings on that particular HDD again, you must
set the HDD status back to R/W (Read/ Write).
HDD redundancy
Setting up HDD redundancy lets your DVR redundantly record a copy of the
videos onto multiple drives as a safeguard against losing all your files in case of
disk failures. This process is also known as mirroring. You must have more than
one HDD in your DVR to set up HDD redundancy.
Redundancy significantly reduces the storage capability of the HDDs. As a result
you need to double your capacity to record video over a given time.
