For the record, I just find proof of purchase of my dns320l. In the next Saturday, will have only 13 months bought (6 November 2013). I confess that I find very "strange" that equipment start fails, a few days after your warranty has expired...
Hi,
I also got the blue LED blinking from hell after using the NAS for over one year. I only got one year warranty from the store but when I created a dlink support case they informed me that I have two years warranty from dlink on the DNS-320L. This was one of the responses from the support center:

Hi,
If power is blinking blue, it means the device is booting/restarting.
The other 3 leds front of dns-320l are for usb and for hdd`s(left and right).
The LAN port is equipped with 2 LEDs:
-The LED on the right will illuminate solid green for a good connection and will blink during data transmission. If this LED is off, check the connection/cable to the device you are connecting to.
-The LED on the left will light solid for a Gigabit connection and will remain off when connected to a 10/100 device.
According to your description it seems that your DNS-320L is faulty.
If reset doesn't help to solve the problem, then there is not much more to do. Reset is located at the bottom panel of your DNS-320L. Press and hold this button for more than 5 seconds to reset the unit to factory defaults.
You have a 2 year warranty for DNS-320L.

Now I'm waiting for the RMA number to put on the package and return the NAS to dlink...
