I am upgrading my DNS-323 from 2X 500GB to 2X Seagate ST2000DM001 2TB. I have put each drive into an USB enclosure and formatted them to EXT3. Both were completed successfully. When I plug the 2 drives into the DNS-323 and log in through the web interface, the standard wizard asked me to set up the drives in "stand alone, JBOD or RAID 0 or 1". After I chose RAID 1, the NAS went to format the drives again. At the beginning, the status bar keeps going up but when it hits 10%, the bar goes up very slowly (about 1% every 5-10 mins). Then after it reached 25% or so, the NAS went offline. The "hard drive lights" on the NAS keep flashing but I cannot log back in through the web interface or cannot find the NAS using the DLINK easy search utility. I waited over 24 hours for something to happen but nothing. I cannot even shut down the NSA by pressing on the power button and have to disconnect the power.
After that, I plug the power in and the NAS comes online again. Through the web interface, I choose "stand alone" this time and it went on to format my drives. Same thing happened and I have to unplug my NAS.
Does anyone know what happened? Is this another unsupported drive issue? If so, other than the WD Green, what other 2TB drive can I use? I don't think that particular model in the supported drive page is available anymore.
