I get my files off msdn and burn them onto CDs/DVDs to use. For some reason, this is giving me the biggest heartache ever. My laptop's CD burner is busted it would seem, since there's a 1 in 5 chance that the CD would actually read after burning, but thats not the problem, I managed to use two different computer to burn. I checked the Hash for the download and it seemed fine, and my main questions is this: Is there any way to check the burned CD for any corruption? Thanks a lot, Chris Another question, could I be getting these "file was corrupted" or not copied correctly due to hardware issues possibly but not only ram and HDD?
