Hi
Same problem here with DNS-315 server.
After startup, the white power led is blinking, and the HDD led is orange.
First I tried with "clean" HDD (not formatted), then I formatted it to NTFS, the problem remains unchanged.
As for connection, I tried to do it wireless, then connected my notebook to the router with ethernet cable, and right now the DNS-315 is connected directly to my computer with a cable, and the error remains:
After I select the device, the progress bar starts, and then it shows the "TFTP server error occured" message.
I have seen the "firmware update" suggestion, but on the D-Link site, it only shows the 1.0 firmware, so I guess it is on the device already...
