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.

I might add that I see nothing about bus speed. The default for linux
has been 33Mhz for IDE systems (adding idebus=133 quadruples drive
speed).
I don't know about your system's maximum bus speed or your drives.
