I have just gotten a synology ds112+ and a WD red 3tb disk. When I am copying large amounts of data, tested with 50gb the ds112+ stops at a random point. This is done from my windows 7 laptop by 100mbit Lan. The status and Lan leds are green but the hdd led is not blinking. I also can't access the ds112+ in any Way and the only thing to do is to pull the plug. Any ideas?
