I have an Intel DG31PR motherboard and I have a western digital WD10EZEX 1 TB Hard drive which is SATA III. Can any one help me with the jumper settings to force the drive to run in SATA II mode? And I would also like to know if IO Crest SY-PEX40039 pci card any good?

SATA3 uses the same connector as SATA2.
so, SATA 3 and all SATA' devices are considered backwards compatible, that is if you connected a SATA III hard drive to a computer that has SATA II built-in, the drive will only operated at the speed of SATA II level. In effect, you'd not get any better performance that you would with a SATA II device (and waste your money you paid extra to get SATA III).

the PCI-e card with SATA 3 can help, but its not the best option
