I bought a DNS-320L around feb/march of 2013. I mounted it with a 2TB and 4TB Seagate HDD. Up until a few days ago it was working perfectly. But suddenly I am having the following problem. I did not drop it or anything. It was just working one day. I disconnected it from the power to move it, and then it was not working properly.
When I turn on the power, it is making a beeping noise. The power, and both HDD lights are on at blue (not flashing).
But the funny thing is, I have tried both HDD's on both bays one at a time. And as long as I dont put both in, it works fine. Both HDD are readable from any bay, unless I put both in at the same time.
I also noticed that the fan at the back is not running.
Any ideas on what might be the problem and how I can fix it?
Thanks for any help.
