Setting the HDD property
You can change the behavior of your HDD by changing its property. It can be set to
redundancy, read-only or read/write (R/W).
AN HDD can be set to read-only to avoid important recorded files from being
overwritten when the HDD becomes full.
Before changing the HDD property to “Redundancy”, there must be at least two HDDs
installed in the recorder, you need to set the storage mode to “Group” and one of the
other HDDs must be set to R/W. See “Setting up HDD groups” on page 116 for more
information.
Note: Ensure that the HDD storage mode is "Group" before setting the HDD to read-
only.
To change an HDD status property:
1. From the menu toolbar, click System Settings > Hard Disk > HDD Information.
2. Select the HDD whose property you want to change.
3. Click the Edit icon . The Local HDD Settings screen appears.
4. Click the desired HDD property for the selected HDD.
5. Click the group number for this HDD.
6. Click Apply to save and exit the screen.
Note: Once set to read-only, the HDD cannot be used to save recorded files until it
is set back to read/write (R/W). If the HDD that is currently being written to is set to
read-only, the data is then recorded to the next HDD. If there is only one HDD
present, setting it to read-only means the recorder cannot record.
7. Click Back to return to live view, or continue configuring the NVR settings.
Checking HDD status
You can check the status of any of the installed HDDs on the recorder at anytime.
To check the status of an HDD:
1. Click System Settings > Hard Disk.
2. Note the status of the HDDs listed under the Status column.
If the status is listed as Normal or Sleeping, the HDD is in working order. If it is listed
as Abnormal and has already been initialized, the HDD needs to be replaced. If the
HDD is Uninitialized, you need to initialize it before it can be used in the recorder.
Refer to “Initializing HDDs” on page 115 for more information.
Note: This information is also available under System Settings > System Information
> HDD screen.
