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 turned off abnormally, i.e. by pulling the AC power
adapter out, and then turned on, the product may reconfigure its RAID

If more than two RAID configured HDDs are broken or removed from the
product, the RAID configuration will malfunction, causing data loss.
During use of the RAID, you should never perform “Remove HDD” from

If any one HDD of the pair fails during RAID operation, it is necessary to
replace the defective HDD as soon as possible in order to restore the
system stability.
