If your NVR supports to install multiple hard disks and more than 1 hard disk is installed in your NVR,
you will see this menu. With Disk Group function, you can assign different cameras to be recorded into
different groups in order to reduce the loading on a single hard disk and extend the life of hard disk.
1. On the Disk list page, click on the edit button
of the hard disk you want to configure, and
then select its Disk Type and Disk Group.
2. Go back to Disk Group page, choose a Disk
Group Type. If all the hard disks are set as
Read Write mode, only Record Disk Group
available to choose here. If one or more hard
disks are set as Redundant mode, Redundant
Disk Group will be available to choose here.
3. Choose the Disk Group.

disk(s) in the selected group. Maximum 16 cameras can be recorded in a group.

5.6.1.2 - S.M.A.R.T
This function is used to display technical information on the hard drive installed inside your NVR. You can
also perform a test (there are three types available) to evaluate and detect potential drive errors.
Self-check Type: There are three types available:
• Short: This test verifies major components of the hard drive such as read/ write heads, electronics and
internal memory.
• Long: This is a longer test that verifies the above as well as performing a surface scan to reveal
problematic areas (if any) and forces bad sector relocation.
• Conveyance: This is a very quick test that verifies the mechanical parts of the hard drive are working.
When performing a test, your NVR will continue to work as normal. If an HDD S.M.A.R.T error found, the
HDD can be continued to use, but there will be a risk to lose recording data. It is recommended to replace
a new HDD.
