Step 1
Click the [Execute >] button on the "Change the oper-
ation mode of HDD" section.
→ The "Change the operation mode of HDD" win-
→
dow will be displayed.
Step 2
Select the desired operation mode of HDD, and then
click the [Start] button.
Images and audio from the cameras will be recorded on each HDD in order.
The same images and audio from the cameras will be recorded on 2 HDDs like HDD1
and HDD2, HDD3 and HDD4.
When one of the 2 HDDs is replaced with a new one, it is possible to copy data (Mirro-
ring recovery) on the other HDD to the replaced HDD. This product or the extension
unit requires 2 or more HDDs.
Even if one of the HDDs becomes faulty, recorded images can be recovered using the
other remaining HDDs in this mode. This product or the extension unit requires 3 or
more HDDs.
Even if 2 of the HDDs become faulty, recorded images can be recovered using the
other remaining HDDs in this mode. This product or the extension unit requires 4 or
more HDDs.
Step 2
Important:
• When the operational mode of HDD is changed
(except the case that the operational mode is
changed from the Mirroring mode to the Single
mode), all data on the HDDs will be erased.
• When "Operation mode of HDD" is changed, the
recorder will be automatically rebooted.
• While operating in RAID5 mode and RAID6 mode,
you cannot add or remove the one HDD unit
described on page 74.
• While operating in RAID5 mode and RAID6 mode,
you cannot add the HDD where video has been
recorded in Single mode or Mirroring mode, and
playback as playback use only HDD.
• The capacity of the HDD in the Mirroring mode will
become almost half if compared with the Single
mode.
• When the operational mode of HDD is changed
from the Mirroring mode to the Single mode, the
status of the HDD will turn to "Playback-only".
