Ok cheers.
Have also found my new hdd to have a jumper that offers a J4 or Partial setting. The J4 setting is the 1.5gb option (my mobo isn't sata II) which is what I need. Turning the disk over so that the component board is facing down, the diagram suggests that the left position is the 1.5gb option. It was set to the right hand position as develivered, so I'm assuming that is the sata II setting?

P.S. The drive is a maxtor diamond max 300gb sata II
