I just finished my first ever build with the i5 and a Gigabyte UD3r MB. I have a WD Black 640gb bare drive I am trying to use as my HDD. In the BIOS it is recognized and set to master sata1 and is being used as IDE. The problem is when I try and install WIN7 from the CD Windows doesnt recognize the drive when I need to select a location to install. I am not sure how to get it to see this drive
