Ok, here’s how my story goes. One day Windows XP (SP2) decided not to boot, so I thought I must have lost my WD Raptor drive which has the OS installed on it. In the process of swapping out with a new drive I found that if I removed another one of my HDs (WD250GB SATA1) the WD raptor boots WXP right up. I’m confused, how can a non-boot drive (i.e. a storage drive) interfere with the ability of another drive to load Windows? The BIOS recognizes the WD25O, but WXP refuses to load when this drive is installed. This is not a RAID set up. I have files on this WD250GB that I absolutely MUST have. How can I get to them?
Check you settings in your bios if your board is raid capable. You may have a setting trying to look at the 2 drives as a raid set up. Of course this is without knowing what your set up is!
