I always forgot to add things. That too. That was my first guess on why I was freezing.
It's a weird freeze though. My music will start looping a second over and over and I can still move my mouse around and click stuff. But as soon as I click stuff, what ever I clicked freezes. If I press start the menu gets frozen open and I have to do a hard shutdown.
My HDTach is below.
I just RMA'ed one that was doing the same thing your are describing. With WD's own utility I was getting cable errors.. but there was nothing wrong with the cable (tried the other drive on it and it was fine)
RMA that sucka.. (I know it stinks)
They also sent me a black topped one instead of the silver top that I had.. so now my drives dont match..
