DVD/CD-RW does not read CD or DVD

I am running Windows XP and have installed two devices. A CD-RW and a DVD/CD-RW. They both show as functioning properly in the device manager. I have also checked in Administrative Tools/Computer Management/Disk Management and both show as Healthy and read the size of the CD. I am sure I have loaded the most up to date drivers for both running on Windows XP. However, nothing I do provides a fix to read the CD's or DVD that work in other PC's.

Any ideas?

R_manic, thanks for the reply. I am using a Samsung CDRW/DVD SM-352B and a ACER 36X CD-RW. I also tried a CD-RW from my other computer that I know worked and it did not work in this computer. I also checked the IDE Driver which seems to be up to date.

One other thing. When I go to check what is on the disk in Windows Explorer it ask to "Please insert CD" even when I have one in there. I had a CD-RW in installed that did not do this. Just blinked a yellow light so I put in another one. All the drives that I beleive work have the "Please insert CD....." Message.

Any other thoughts?
