OK, so amazingly everything finally was in stock and ordered and even put together (Big Thank You!!). The system booted up and everything looks like it's running as it should. But here's my question, should I format my hard drives before loading Vista, or are they already formatted? When I went to install Windows Vista (my two 640GB drives in RAID 0, 1TB drive disconnected) the option to format was not able to be clicked. It appears that the Vista load went fine, but before I start loading all my drivers and programs, I just want to double check about formatting the drives.
