Like Aryeh, I missed the jumper.

Well 'significant' to a laptop on battery, anyway. Given that single-drive setups seldom stress even UDMA 133 over the course of reasonable time spans, does anyone know if: A) SATA 300 needs yet-again more power than SATA 150? B) running down-shifted to SATA 150 might actually be a better plan anyway in some circumstances? Easier to maintain data integrity comes to mind as well as power budget. Just curious... Bill
