	It's not actually connected to the Promise, it's connected to the
VIA controller plugged in right next to the Seagate drive. The Promise
controller has ad4 (SATA) and ad8 (PATA) connected to it, the VIA has ad10
(SATA), cd0 (SATA) and cd1 (PATA) connected to it. I am deeply suspicious
about the mention of ata4 for two different devices (ad8 and cd0) connected
to two different controllers.

	It doesn't even get recognised as being present if I connect it to
the Promise RAID controller, I made that mistake when I first connected it.
