Here's my problem. I set up my comp several months ago and believed that everything was correct and I was running RAID 0 w/ my two WD Raptor 150's, Not the case as it turns out as I noticed that one of the drives was not moving at all yet everything still ran fine. I have a couple of questions now though: one, is there anyway to get my drives into RAID 0 w/o killing my system, or how do I get windows to see the other hard drive, cause right now it's like it doesn't exist. I am running everything on a EVGA 680i mobo w/ the P23 bios. Thanks in advance for any help.
