My dad was trying to copy (legitimately) some CDs using Nero6, but for some reason, the copy goes well, but the cd will not work properly. It gets all the tracks right, but when you try to play them, you get a constant tap noise instead on all tracks. Apparently he had installed some other program to do with CD copying before, and I think that might have messed something or another up. The drive reads the CD properly, and all other CDs as well. Its not a protection issue, because the CD has no protection whatsoever. Not to mention that copying it on another computer works. We actually thought the DVD burner had burnt out (4-5 years old?) but when we replaced it with a brand new one, we had the same problems. I made an image onto the computer itself, and used Daemon to run it, and it had the same constant tapping noise. I know this sounds very iffy, but so there is no confusion, we're making copies of church sermons. Anyone interested? Anything that might help?
