I have a pro 6 with a 9tb volume and a 6tb volume. About once a week, the whole drive drops off the network and can't be accessed through CIFS or the web admin interface. It doesn't turn off, the light on the power button is still on and the fan is still going, but it basically acts like it's off. When I press the power button on the unit, nothing displays on the LCD panel as it does when the unit is working properly. When I press and hold the power button to power off and then power back on, everything is working fine again.Any ideas on what would be causing this and how I can fix it? It's a big problem because the only way to refresh the system when it's locked like this is a manual physical reboot, which I obviously can't do when I'm trying to access it remotely.

Does it respond to ping in the locked up state? Also, have you checked the logs and disk health?

How do I do a ping (windows)? Disk health is fine. Can't see anything in the logs that indicates what's going on. Any particular log I should be looking at in detail?

You can do a ping in windows by opening a cmd box (enter "cmd" in the "search programs and folders" textbox). At that point you will see a window open up with a black background. Select it, then type "ping xxx.xxx.xxx.xxx" (xxx's are the NAS ip address) and then press enter. you should see four responses that say "Reply from xxx.xxx.xxx.xxx: bytes-=32 time<1ms TTL=64" There will be some other stuff also (statistics, etc).

Hi coricidin12, Could you send logs to me?

I checked logs, you installed PlexMediaServer add-on, it invoked oom-killer,

I also found two driver's FW is CC4B in your NAS,
There is issue in old FW,
http://forums.seagate.com/t5/Barracuda- ... rue#M28884
it should use firmware CC4H or newer in Netgear HDD HCL.
Please update their FW,

Did you ever get this figured out? My Pro 6 does the same thing. about once a week, nothing responds, power light on, push power button and nothing.

I have the exact same issue; usually under heavy load. I cannot ping the device. the only solution is a reboot.
