DVD / CD-RD does not recognize any disc inserted I am having a problem with my DVD/CD-RW. It will not recognize any disc, factory pressed or otherwise, that I insert into it. I have tried: 1. Uninstalling/Reinstalling the drivers 2. Uninstalling/Reinstalling the hardware. 3. Deleting the upper/lower filters from the registry 4. Updating the firmware. 5. Uninstalling/Reinstalling any CD/DVD writing software (worked for a couple days) 6. Tried system restore, but system says it is unable (go figure!) 7. Transfer mode is DMA on both the primary and secondary channels I managed to get Dell Hardware Support to talk to me even though I am out of warranty. They performed some check and I was told that my drive was fine before they realized my warranty had expired. They said my problem was a software issue--something about conflicting drive controllers. Odd thing is, it was working one day and wasn’t the next; I hadn't newly installed or updated anything. My current Dell Vista 400, XP Pro, is a system replacement and only about a year old. Before I completely reinstall my OS to see if that works, does anyone have any suggestions for where to look and what to try next? Thanks for any suggestions offered.
