RAID array is damaged.
Selecting RAID5 configures 4 HDDs to 1 RAID array. RAID5 uses 4 physical
HDDs as 3 functional HDDs. For instance, configuring HDD1, 2, 3, and 4—
while each one of them is equipped with a 500GB HDD—to RAID5 displays
the system's functional HDD as one 1.5TB RAID. In RAID5 mode, no data is
lost even if one of the four HDDs is damaged.
To configure a RAID mode, HDDs must be the same size. It is highly
recommended that you use the same brand and model HDDs to configure
RAID.
RAID settings are available only for internal HDDs.
Building a RAID mode using 4 x 500GB HDDs takes approximately 3 hours for
RAID1, and 4 hours for RAID5.
Caution
Changing the RAID settings to a new mode automatically deletes all data
in the HDDs of the product, and new video files are not saved until the
new RAID mode is completely configured.
When the product is abnormally turned off, i.e. by pulling the AC power
adapter out, and then turned on, the product may reconfigure its RAID
settings automatically to ensure the integrity of saved data. While a new
RAID mode is being configured, existing data is not lost, but new data
will not be saved either.
If more than two RAID configured HDDs are broken or removed from the
product, the RAID configuration will malfunction, causing data loss.
