Hi - just to add my working hard disc in here ( not without problems though ) - Hitach HDS72202 (2TB model).

Couldnt get it to format under the vix firmware no matter what i tried so i had to revert back to stock firmware, format, and then put ViX 2.0 back on and set up again. I did try a 3TB in there as well and it wouldnt only see 800gb of the 3tb but i must confess i didnt do too much on that disc as it wasnt intended for it but i just thought id try - that was a hitachi also.
