They are a ST2000DL003 and a ST32000641AS both nominal 2TB hdd's.

lets not quiblle over the definition of terabyte, be it 1,000,000,000,000 or 1,099,511,627,776 these are 2TB drives and are either equal to or less than 2 terabytes. I strongly suspect that the Marvell chips are the problem, hoping that a firmware or driver update will fix it. The Ga-P67A-UD7-B3 is a newish board, and 2TB hdd's have been around for ages.
Of course if someone out there is using a Marvell controller with a 2TB drive this could sort the matter out.
