As I mentioned, the bios recognizes my hd as an udma4 capable device, so
it's not a cable issue, I think, the driver won't detect properly the
cables. By the way, it would be good to have driver parameters, that
help setting the prefetch buffer and post write buffer on, because on
the secondary channel, it's off by default, I'm using powertweak to
enable them. Thx.
