Just an update to advise that I have solved my issue by: Replacing the SATA cables. Resetting all power connectors.
Setting the bios SATA to enhanced from auto. Adding a IDE delay of 5 seconds to bios set-up. HW Details: AW9D-MAX (Intel i975-ICH7), BIOS 6.00 PG 04/18/2007 Quad Core 8G RAM 3 x 500GB HD.
