I tried to copy a file from a DVD to my hard drive, and I had this error stated in the title. I tried to go to microsoft support or whatever it is called, and their advice didn't work. For some reason, it just doesn't work for just this DVD. It works for the other DVDs. Now, where can I find any info on which driver, (primary or secondary), which of the 3 primary or secondary, (total of 6 (3 primary, 3 secondary)), and which device (0 or 1) is my DVD drive connected to? Maybe I should have changed my title to "How do I know where my DVD drive is connected to? Primary? Secondary? Which Secondary out of the 3? Device 0 or 1?"
