kutless, While i am in the process of becoming newly acquainted with SATA (due to a recent acquisition). Apparently there can be only one SATA device per Data cable. So not knowing if the SATA cable provided in your computer has more than one connection point,apparently only one should be installed(device) per cable to the motherboard. Because my computer did not include SATA cables (power or data) and i have yet to purchase them i was concerned that your cable might have more than one connection available. truenorth
