When you set RAID for individual HDDs, the "
HDD connection status changed.
” message will pop up along with a beeping
sound, and this is normal.
-
When configuring RAID, NVR was expecting five or more individual HDDs. But the number of HDDs is reduced as the
RAID is configured. This does not cause any problem to NVR recording and the use of RAID and HDDs.
Even for general HDDs, the number is often reduced while using, and it does not cause any problem to NVR recording
and the use of HDDs.
