This is for my newly acquired TCD652160 which I installed a 2tb WD drive into and seems to have gone smoothly...but... Sometime in the middle of the night it restarts and gets stuck on Powering Up. If I unplug it and plug it back in it boots fine. This has happened twice and I'll of course see if it happens again tonight but has anyone else had this happen? Is there maybe a sleep function on the WD drives? Is this a sign of a dying power supply? How can I test things to determine what the problem really is?
