If it wasn't for all that, I'd have suspected a small power issue.

I recently ran into an odd problem of how my PSU has its rails split up 
between different cables. If I had all the hardware in the box hooked up 
with the normal "black" cables from my PSU I'd get errors from one of my 2TB 
WD Green's. But if I moved the drives, or the GPU to the "red" plug (modular 
psu), everything worked. I assume the rails on my psu were split up 
absolutely retardedly, causing the main 12v rail to be shared between the 
cpu, all add-on devices, AND the non-modular PCI-E cable for the GPU 
(8800GTS), causing that rail's voltage to drop below spec.

But it sounds like maybe your SATA chipset might not be supported in AHCI 
mode (which you really want), and might have issues in IDE mode. But given 
that its an intel chipset you'd think it'd have perfect support :o So I 
don't know.
