I just finished my AMD 64 build and I'm curious. I'm using the Silicon Image controller built into my A8N SLI Deluxe. For the time being I'm just running JBOD till I can get a third 250GB Drive and do RAID 5....One Drive of mine is blank and is already registered with the RAID controller...however, another drive has a TON of Data on it. If I enable it as JBOD in the controller...will it affect my data in any way?
