XP Pro SP3 This is a very strange situation. I started to copy a CD, one that I have made copies of before. The program (Deep Burner) froze after caching the files (that has never happened before), and after a while I gave up and hit the power switch. Today, I decided to copy the files to the hard drive first and then create an iso, so I could make several copies faster with less chance of trouble. The copied files read at 1.14 gigabytes! I said "What tee eff" and checked the original CD: 1.14GB again. It should be around 549MB. Other CD's are all right, Windwoes reads the right size -- it's only the one that was involved in the crash that is misread. Doesn't matter if it's the original CD or a copy on CD or HD, it's 1.14 gig. I've been cleaning temp files, combing the Registry, wottever. And yes, I've rebooted again since the mishap. So, any ideas on what could be giving the wrong spin to that one CD? Where is Windows storing the erroneous data? It's not a dire problem, I can do the copying on another machine. But I would certainly like to know why it happened, how it might happen again. And how to fix it
