Help - Readynas Ultra 4 Plus - I think the Data is okay, but the Readynas is not functioning

So an HVAC tech came out and flip the circuit breakers without my knowledge.  Now my Readynas Ultra 4 Plus is not functioning properly.  At first I could see it on PC.  i could navigate to it by IP and by Hostname.  however when I double clicked on one of the shares, it would error out  with "network name no longer available."  I did a quick google search and saw something about DLNA, however I don't even have DLNA enabled.  So thought I do some troubleshooting.  I tried to update the firmware and even though I am positive that I downloaded the correct firmware, the GUI states that the firmware file is not supported with this architecture.  Update over the internet doesn't work at all, it just sits there when I click the button.  So then I thought, hmm, why don't i try disabling CIFS and re-enabling.  Now it won't re-enable at all. Raidar reports everything is healthy.  The ReadyNas Admin page also seems like everything is okay,  However I just can't access the data.  For isntance, the home page shows Volume c: Online, X-Raid2, 4 disks, 99% of 5543gb used.  Also the health page shows everything as OK.  There is nothing in the logs.  So what are my options? What would be the best way to get my data?  

1) Can I go and get 4 blank drives.. Restore to factory?  Then try to put my old drives back in?  

2) Do i have to get something like ReClaime or R-Studio to recover my data?

    b)  If so is there any good step by step guide on how to do it?

I wish there was a way to do restore the OS to factory without losing the data.  I am sure the Raid Partition is in tact, it's just the OS is malfunctioning.  Please any help would be greatly appreciated.
