I have a Dell XPS 420. It had/has a 750 GB which came with it when shipped. I recently added a 2nd drive, a 1 TB. When I was installing the drive, I noticed that the top DVD-ROM was connected to the RAID Controller which I thought was odd. I plugged the top DVD-ROM into one of the other SATA ports on the motherboard and plugged the 2nd hard drive into the port where the DVD-ROM was.
I booted up and hard drive was found and everything appeared to be working correctly. Fast forward to today when I put a CD into the top DVD-ROM and it will not read it. As I did some searching, it seems the drive isn't being detected.
I only have one other SATA port on my motherboard that I can try. Is there anything else I can try to do? The drive is getting power.

I assume the DVD-ROM drive worked fine (with the same CD you tried today) prior to moving it off the RAID controller?
If so -- is it possible AHCI mode is enabled in the system BIOS, and that the DVD-ROM that came with your system isn't AHCI compatible? This may be why Dell stuck the DVD-ROM drive on the RAID controller (which may not be configured for RAID at all; could be operating in JBOD with AHCI disabled on the RAID controller). -- Making life hard for others since 1977. I speak for myself and not my employer/affiliates of my employer.
reply to MJimLay It was working when it was connected to the RAID controller. I'll check the BIOS for that setting and see if it's enabled. I thought it was a little strange that they connected it the way they did, I just hope they didn't do that because the other controller has issues.
