Setting the HDD to read-only

1. From the menu toolbar, click System Setting > Hard Disk .
2. Select the HDD you want to set to read-only.
3. Check Read only .
4. 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.
Note: You must set the storage mode of the HDD to Group before configuring
the redundancy. See “Setting up HDD groups” on page 122 for more
information.
To set up HDD redundancy:
1. From the menu toolbar, click System Setting > Hard Disk > HDD
Information .
2. Select the HDD to be used for redundancy and click Edit .
