How to install two CD drives

Hello all, I am in the process of building my first computer and I’m running into a small problem. I have two drives that I am installing and I can install them both separately no problem, they work fine. However, as soon as I plug in the second one the machine only sees one drive. In other words, although both drives are plugged in, if I go under my computer there is only one drive visible. I’m not really sure how to make the system see both drives simultaneously. Any help appreciated. Thanks in advance.

 

First, thanks for your response.

Yes, they are on the same IDE cable. I think I have the master/slave set up correctly. I have the first IDE connector coming off the MB connected to the drive I want to be slave and the second connector on the master. I did notice that if I right click the Drive in my computer and click 'eject' that both drives open up. This is the first time Ive done this so Im sure its something simple that Im just missing.

Thanks again

 

If you are putting them on the same cable, put the master at the end of the cable and the slave on the plug below it.(in the middle). A second option is the put your master on the 1st ide channel as master and then put a cable in for the 2nd ide channel and set the second drive to master and place it at the end of that cable.
