Over the past hour I got to thinking and realized that I had not given all the info a post of this sort should have, plus, I’ve learned a few things since then.
First, this is on a Win-XP-SP3 system, Asus board, 2.93 Pentium-4, 2 G RAM that I built and that has been totally bullet proof … no exceptions.
Second, I found that the drive had stopped reading only data disks … it played a video VOB file just fine both in VLC player and Power DVD … interesting.
Third, I took the “bad” disk to a friend who has three computers in his house … they all read it just fine.
Lastly, I thought back to anything I had changed or has seen change in the system recently and narrowed it down to changing “Autoplay” to not bug me about what it should do with each disk.
I changed the Autoplay for “Mixed Content” to ask me each time and that did not initially work, but after a re-boot … it now seems to … go figure.
So … I’m not sure at all that I’ve found the problem, but, for now, the drive is reading data disks again.
I hope I didn’t cause anyone to spend any time on this and my apologies for writing before I had exhausted ALL possibilities.
