Since this appears to be a laptop, you could try purchasing an external hard drive case (one that it usable/certified on larger hard drives) and connect it directly via USB port and see what Disk Manager then shows. I believe that OtheHill is right when he says that your docking stations were never intended to be used with hard drives of that size so their firmware cannot handle the larger drive capacity. You can also check with the manufacturer of the docking stations and see if there is a way to update their firmware.
You have to be a little bit crazy to keep you from going insane.
