Heya AW,
The very first thing to test is to try booting to a CD or DVD in each drive. If both drives work without a problem when you boot to them, then you know it is a software issue. If that happens, I'm guessing you have Roxio Drag To Disc installed, or some other similar kind of program. I have seen Roxio's Drag To Disc cause identical symptoms to yours on several occasions. I would try uninstalling that or any burning software you have and at least see if autoplay works and if the drive then recognizes disks.
If one or both of the drives do not boot to a disc, then it is hardware. Judging by your description, it seems like one (or both) of your drives could be defective. A couple things to test would be to try each drive in the master slot of the IDE cable
by itself. Be sure to
change your jumper to master or cable select when you move the drive to the master port. If that doesn't help on either drive, try changing out the IDE cable, and/or changing the IDE port that the drives are connected to and then testing booting to discs.
Hope that helps!
