Bios Version : F7
OS : Windows XP Pro SP2
Controller : NForce4 Ultra (Not Sil)

I seem to be having an issue whereby the K8NXP-9 seems to hate SATA-II
drives, to the point where my Hitachi Deskstar 7K250 just locks up the whole
system after sustained read or write operations in Windows. Tested the
drive, - works perfectly for hours when Suse Linux is installed onto it.

I've had to fall back to using an IDE drive on this mobo as SATA simply
isn't stable.

Has anyone else suffered this problem or found a solution? Pretty
frustrating.
