This looks right to me. One main PIIX4 ATA controller with two
independent IDE channels (usually referred to as a Primary and a
Secondary IDE controller). Usually the PC BIOS will allow you to turn
on/off these channels independently. Does your bios allow you to turn
off the Secondary?

I don't think the HDD is being detected twice. Try this instead:
% sudo atacontrol info 0
% sudo atacontrol info 1
