So after finally getting my system up and running, I had a set back when I plugged in two 1T WD external HD's. Turns out when booting with the external HD's connected via USB the bios/cmos resets. I cannot enable the host clock control with the hd connected. Anyone have any thoughts?

System specs:
Q6600 @ Stock 2.4Ghz
Crucial Ballistix Tracers 4x1gb
ATI HD2600XT 512mb
Corsair 600W PSU
