Not only that, but I bought a new SATA drive at about the same time as I
switched to the DVB drivers.

Did you ever get a good resolution?

I have an ASUS A7N8X Deluxe motherboard, which includes on-board a
Silicon Image Sil 3112A controller; the same one you found to be your
problem.

I suppose that if I can't fix some setting somewhere, then my best hope
is to buy a separate PCI SATA card with a different controller chip;
that would at least be cheaper than buying a new 400GB hard drive.
