My MB has only one IDE connection and all others are SATA. I have/had two IDE devices connected to the IDE port and they work without any problems. I wanted to add a second DVD drive. So what I did was get a IDE to SATA adapter to use with my IDE hard drive and then connect my two DVD drive through the IDE port. The adapter and drive picked up with no problems. As for the two DVD drive, they listed in BIOS but once I get to Windows they aren't shown in Windows Explorer and only seen in disk manager in the graphical view not in the volume list. I've check the connects, I've changed drive jumper from CS to master/slave, took the second drive I add off the ribbon, and put everything back to what it was before doing all of this. Even now with everything back to what it was as in drive connections, the DVD drive isn't being picked up. I've also uninstalled the drive in device manager and the restarted so it would be picked up and installed again. Windows picked it up and installed drivers and still nothing. At this point I can't think of anything else to do.
