I've been running the DNS-320 110 since July of last year without any issues, but just today it stopped mounting on my Mac (OS 10.8.3).
The NAS is configured with two 3TB drives in RAID 1 format. And both drive lights and the power light is ON, on the front panel. As far as I can remember I have been running firmware 2.02 on the NAS.
I have been using the NAS as a Media Server and Time Machine backup. The first symptoms of something going wrong was a message on my Mac, which said I had to create a new TM backup because the old backup could not be verified.
At that point, the NAS was still mounting on my Mac and I was able to access the files on it. But this morning, upon booting my Mac, the NAS did not mount and I got an error.
Now, I am unable to access the configuration panel using the browser and my XBMC media-center which typically accesses the NAS to play videos is getting a network error when connecting to the NAS.
Any thoughts, suggestions, on troubleshooting?
