Why wont my computer pick up my dvd drives

[irntgr x zeus]

Hi,
I just put a second dvd burner into my rig today and i'm having some issues. i already had one installed and it worked fine, and then i put in the new one and it won't recognize either of them. but, when i unplug the new one the old one works and when i unplug the old one the new one works. i don't get it. help please?

i'm using ide drives on a windows 7 based pc.

I assume they are SATA. Go into the BIOS, and make sure all the SATA ports are enabled.

Try running this diagnostic scan.

no, they're IDE. When I start up my PC it says "hardware id cannot be found" or something like that. Then when I ran that scan it said that no optical drives were found. Also when I start my PC a message pops up and says that drive is not ATAPI (I think that's right, could be wrong) compatible.

Check the jumper settings on the drives. One should be set as master, and the other as slave or cable select.

I think part of my problem lies in those settings. It's like my PC is trying to run them both as the master, because under master it has my older burner selected, but then under slave it says undetected. When I start up, a screen similar to BIOS comes up and says that the slave drive is ATAPI incompatible.

Change the jumpers and see if that fixes the problem.

If that doesn't help, check and see if there a secondary IDE controller listed and/or enabled in the BIOS?

okay, well I got both of them to work. I just flip-flopped their positions. Put the new one where the old one was and the old one where the new one was, so that way the newer would be the master and the older the slave, and it worked. It's crazy that it could be that simple, but hey, I'll take it. Thanks for all the help and tips though.

Yep, that sounds like jumpers for sure. Good to hear it's working.
