how many hard drives are inside your computer?

example i have 3 a western digital a samsun and a hitachi.

i use the hitachi for my vista install so what i do is:

1 open case
2 unplug sata power cable from psu to hdd on w/d and samsung
3 unplug sata cable from hdd but leave it connected to the motherboard on w/d and samsung
4 i then install windows on to the hitachi.

as you bought the hdd and psu etc im assuming you have fitted them in the pc yourself?
if so then all you do is the cables you plugged in to the samsung hdd you, just unplug them again and then install windows unless, you are installing windows on to the new hdd and have spare one's in your, pc then they would be the one's you unplug.
