Pro 6 on 4.2.30 suddenly reported Volume dead

Hi All,

I'm at a complete loss as the current issue I'm experiencing is unlike anything I can lookup. Any help or ideas would greatly greatly be appreciated as from what I can tell the data is there but I can't access it via Windows. 

About 48 hours ago, my ReadyNAS Pro 6 set to X-RAID2 w/ dual redundancy middle of streaming a video and the video was suddenly not found, checking on what went wrong RAIDar suddenly showed that the volume was reported "DEAD" and then that Disk 6 failed, I immediately pulled the drive and performed Seatools for Windows on the drives with showed no issues on any test I can run on it (Seagate NAS HDD ST3000VN000 3tb). No other drives reported any issues and I believe that's to be accurate because I can access the data via another means

I insert the drive back and the Pro 6 immediately recognizes this and begins a resync'ing of the drive to the array which just finished this morning and it succeeded to resync the drive but it still shows Volume is still dead. 

one thing I noticed though.. 

-- To test if the data was there I was able to log in via Plex and stream all the movies, photos and everything else I have parked on the NAS.

-- Additionally Transmission is also running without any issues and I'm able add/remove torrents

I did notice that everything under "Standard File Protocols" was now unchecked and any attempt to toggle it ON just keeps it turned off. So that's probably why I cannot access/map to the NAS in Windows but I'm relieved that the data is there as accessing it via Plex to watch movies assures that its there.  The LED on the physical front door of the Pro6 still reports that the IP address and remaining storage left on the NAS.

1) Is there anything I can do to get this back online?

2) If this isn't salvagable, how would I move the data off if I know the data is accesable?

I'm not extremely proficient on command line, as I haven't used it in a long time but I was able to SSH via Putty into the box and can see the files and directories on the drive using the listing commands I remember from way back when.

Below is what I'm seeing in some of the screens, what's weird is that I don't remember seeing FAN CAS or Temp AUX before. 

thanks for everyone's time in looking and lending their thoughts!
