Thanks for the update, good to know the limit is 8GB for that 8CH 8POE NVR. By the way I put the other 6TB HDD in my computer yesterday and it runs fine after formatting/disk manager Windows 8.1
So far all the problems that I have posted have been solved.

We are having similar strange issues with an NVR-EL-32. For the second week in a row it is stuck in a reboot loop after the Tuesday morning maintenance restart. This NVR unit is about 30 days old and has been up and running for most of that. After about 10 days (2nd Maintenance and last week) of running it started this behavior.
This unit has 3 WD purple 4TB drives and last week when this behavior started I disconnected all of the drives and all of the network cables in order to get it to boot at the direction of a tech at Security Camera King. I then spent the next hour or so trying to figure out why it would no longer boot properly with all 3 drives connected. I could connect 1 and 3, 2 and 3, or 1 and 2 drives up and it would boot but the moment I tried all 3 it would no longer boot properly. I switched cables and even SATA ports around (it has 8 ports) but it didn’t matter.
So just like during my testing, I finally just left 2 drives of the 3 connected. I reconnected my network cables and it booted just fine. I even restarted it a couple more times just to make sure it would restart just fine for the Tuesday Maintenance the following week. Fast forward to this morning (Tuesday Maintenance) and the unit is once again stuck in this restart cycle so I’m heading in to the customer location for more madness.
FYI: during this reboot loop the unit powers on and network connectivity comes up (verified with extended ping) but you never get a display on the screen. If you have the cover off you can witness the LED lights on the MB going to work and then around 3 minutes you can witness it restart (over and over)
the best way to test this issue is by adding one drive at the time and not 2 at the time and test. See the problem is to identify if the issue occurs with one specific drive and not 2. Have try reformat the drives? what is the firmware you are running on both the Ip cameras and NVR?

I picked up an NVR5808 local and swapped out all the drives and they came up fine in that unit. It is very similar the one I purchased from you except the firmware is different and it is only 8 channel but has 8 sata ports. I restarted several times without issues..
The suspect unit is now on our test bench with a couple cameras hooked up and a single drive (I only had 1 spare). I will get the firmware version on the NVR and the cameras tomorrow.
I could not spend much more time at the customer location, just needed to get them up and running since they already had a couple of outages within 30 days. If i cannot duplicate the problem on my bench, I’m guessing you wouldn’t be able to catch it either.
I’ll post updates when I get them.

This mornings auto maintain reboot at 2 am was fine on my 8ch 8poe NVR.
My advice to anyone who has this auto reboot failure is to take out the HDD and reformat it with a computer and then put it back in the NVR and it will reboot normally and then plug in the cameras one at a time. All the cameras at once might lock things up again. Whet you reformat the HDD you just lose the video that was recorded. The settings for everything else is still retained. So don’t be afraid to reformat HDD. I left a power cable and sata cable sticking out of my computer for easy reformatting if necessary.
And power outages are likely suspects in NVR failure to reboot. My last failure to reboot had a short power outage (lightning) the night before the auto reboot. Then when the auto reboot happened the NVR failed. So I reformatted and it was fine again. Then I went to Best Buy and got a UPS uninterrupted power supply for about $69.00 for any future lightning strikes or outages. It will keep the NVR running for 20 minutes without 110 volts. But my power outages are only half a second long. Remember this…..if you turn the system off with the rocker switch on the back of NVR the system powers down in 5 seconds….but it saves data in that short time for normal reboot. But if you unplug the cord from 110 volts the NVR will fail cause the data can’t be saved quick enough. So get a UPS battery backup for your NVR.
And since then I have updated the firmware on my NVR and it is running like a champ for a week now.
NVR’s are a little more sensitive than a DVR but the picture is so clear and worth the setup.
That’s my experience and I hope this helps anyone who reads this.
