I don't think ACHI would help any.
Please what I said again thoroughly, I know he wants to use the hdd for second space, but listen what he says about his main hdd..
What type of hdd is he using mind, also what type of new connector does he have for his new hdd mind ?
I have done this before with ide and sata configurations long ago, sometimes a raid mode in his situation might not do well.
That is why I recommended he try ACHI right after both hdd's show in bios and let him configure it there for windows to finally boot correctly with the new hdd.
Besides that, if his windows 7 saw the hdd, it would begin to install the generic drivers and ask him to reboot to initiate his new hdd.
