Well, forcing such agressive settings like you did is often cause for
trouble. I don't wonder any more. You did not mention such
non-selfdetected settings in your first mail. Communication between the
hard drive and the motherboard hardware using the chipset specific
driver is critical. In most every case you should let the kernel
autodetect the drives settings and not force things.
