My CD Rom drive worked flawlessly.
I swapped it out and installed a DVD player and it worked.
I put the CD drive back in to an empty slot below the DVD drive. It connected it to the same data cable.
The CD is set up 'CS' (cable select) and the DVD is set up as slave (both were set this way by default).
When I did this, the DVD isn't recognized in My Computer.
I took both out and switched postions (wondering if the data cable's connector was bad) and the DVD wasn't recognized, but the CD was.
EDIT I found my answer http://www.pcguide.com/ref/hdd/if/ide/confCS-c.html both need to be CS or master/slave, but it can not be CS with either master or slave.Thanks for reading!
