DSM-G600, DNS-3xx and NSA-220 Hack Forum

I purchased a new DNS-323 yesterday (moving on from the SC-101)with two Hitachi Deskstar 7K500 Drives.

All began well...

Disk drives in.  Lights flashed then after a minute stayed on.  Search utility found DNS.  All configured.  Drives formatted (Raid 0 and EXT2).  All working on my PC and MAC. 

Then the firmware flash....

I downloaded the latest firmware from D-Link, and applied it to the DNS.  The progress bar went to 99% and then nothing further.  I left the PC for 2hrs, but to no avail.  I refreshed the "web browser".  In the bottom left had corner it said connected and the download bar moved slowly, but nothing after another hour but a blank page...

I looked at the front of the DNS.  The lights were best described as "dim" blue and flashing.  I could not find any advice on that status. 

I left it for a few hours.  No change.  I applied the tried and tested technique known as "on and off again".  It returned to the same "dim light status".

I reviewed D-Link's website.  The only suggestion seemed to be a manual factory reset.  This I did.

The DNS started with the main light blinking brightly (the website suggests this may go on for one hour). However, it did not stop.  The drive lights started to flicker (but not so brightly as the main light) and the network light flashed every 20-30 seconds.  However, they did not stop. 

I tried the Search utility.  No DNS found.  I left it overnight.  Still blinking in the morning. 

I tried a reset again.  3 hours on and its still flashing.

Any ideas from the great and the good?

Thanks in advance
