I have my unit configured with 4 SATA 2TB drives. The drive has been mapped. When it is running the OLED diplays only dlink-31F013 (MAC address) but IP address , firmware version and temp titles are listed, not the actual data. The power button does not work at all. I need to pull the adpapter out the back to power down. Powering up is just as irregular. Sometimes I get the OLED screen filled with orange dots....somtimes the partial words systems is booting is displayed. I can view all of the OLED stat information from the web admin page fine. The OLED is unpredictable often requiring multiple power on and off sequences (pull AC plug out the back as the power button is unresponsive). I have a DNS-321 and it works just fine. The 343 is a whole other story. I am not happy with my purchase.
