Lanny or Bill - Sorry I'm loosing track. One of you has three boxes; in boxes #1 & #2 the drives behaves as you want, in box #3 the drive misbehaves. Have you tried the test of swapping the drives in - say - boxes #2 & #3 and seeing if the problem moves with the optical drive or stays with box, #3?
Alan: Today, I removed the Teac DV-516D DVD/CD reader, manufactured October 2004, in Japan, from my daughters box. I temporarily hooked it up in my box. The exact same problem! I could not see the contents of a DVD-R, but, I was able to see the contents of my Knoppix Live CD, without any problem. So, I did not bother with the PITA of removing the DVD/CD reader from my box, and trying that one in my daughters box.
I booted my daughters box with my Knoppix Live CD V. 5.1.1 and it also showed the FC6 Install DVD to be blank.
I suspect:
(a) The Teac DV-516D DVD/CD reader is not supported in this kernel or somewhere else in CentOS 5. or
(b) The DVD/CD reader is somewhat faulty.
(c) However, Windows XP shows it to be "OK" and I can see the contents of the FC6 install DVD OK, in Windoze. Also, I can boot from the CentOS5 and FC6 Install DVD's, without any problem. And, I was able to mount the FC6 Install DVD, in a terminal and install the RPM I wanted to install, without any problems. Thank you, very much, for your time and ideas! Lanny

Lanny - Thanks for the update. I would recommend, therefore, that you replace the CD/DVD-ROM with a modern DVD writer that can cope with CD-RW/DVD-RW/DVD+RW, etc, formats. When I refurbished this workstation, a Dell OptiPlex GX1 (manufactured last quarter 1999 :-D ), I replaced its original CD-ROM drive with a multi-format AOpen DVD/CD rewritable optical drive, model no. DUW1616L and have had absolutely no problem with it at all. I seem to recall it cost me UK£41-00. However once you've done the conversion at the current exchange rate, I don't know if you will think that is good value - or not.
As for all mentions of Windoze, I would trust/believe that about as far as I could spit into a high wind!
Alan.
