CD/DVD Drive Confusion

[Techtronic]

Hello all,
One of the two DVDRWs on my desktop went out recently, and I threw another one in there thinking it would be a quick fix. Well, my comp is not wanting to cooperate. Here's the scenario:

If just the one old drive that's still working is plugged in, it shows in my computer as drive D:

If I plug just the new one in, it shows in my computer as drive D:

If I plug both of them in, only the new one shows up as drive D:. While the comp is still on, if I unplug the new one, the old one takes priority and begins to function as drive D:

While both are plugged in, the old drive refuses to read any CDs or respond whatsoever. As soon as I unplug the new drive, the old one reads immediately.

I am at a loss here, I've tried getting the comp to recognize new hardware, update drivers, etc... to no avail. The new drive didn't come with an installation disk or anything because I scavenged it out of another tower I had sitting around.
I appreciate the help in advance.

Most likely you have a jumper problem and these drives are IDE. One needs to be set to master and the other one to slave or both need to be set as cable select.

Yep, they were IDE. See, I knew you had to do the master/slave bit with hard drives, wasn't aware you had to do it with CD drives, too.

Thanks so much for the help, works great now.
