6. Change the HDD status property of the selected HDD. See “Change the HDD status property” below.
Change the HDD status property
If you have more than one HDD installed, you can change the behavior of a HDD by changing its property. It can be set to read-only or read/write (R/W). The storage mode must be set to Group before setting the HDD property.
A HDD can be set to read-only to avoid important recorded files from being overwritten when the HDD becomes full.
To change a HDD status property:
1. From the menu toolbar, click
Storage Management
>
HDD Information
.
2. Select the HDD whose property you want to change.
3. Click the
Edit
icon . The
Local HDD Settings
window appears.
Note: The Edit icon is only available if there are at least two HDDs installed.
4. Click the desired HDD property for the selected HDD: R/W, Read Only, or
Redundacy.
5. Click the group number for this HDD.
6. Click
Apply
to save and exit the window.
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.
Set up HDD sleep mode
You can set the HDD to enter standby mode, or sleep mode, after a period of inactivity.
Sleep mode decreases the power consumption of a HDD.
To enable HDD sleep mode:
1. From the menu toolbar, click
Storage Management
>
Storage Mode
.
2. Check Enable
HDD Sleeping
to enable sleep mode. Default is Enabled.
3. Click
Apply
to save the settings.
