Hi, Recently my cdr drive has been failing when burning audio or data cds. The error message usually reads that there is a problem with the CD, but I have tried a couple different media types, all with the same result. If the burn process completes, there is usually a visible gap on the media that prevents it from being played or read properly. I have tried several different programs, including Nero, RecordNow, and Alcohol, but all seem to produce the same result. I'm assuming that the problem is with my burner, but I just wanted to make sure that there isn't something I can do to fix it, or clean it before I have to take it in to be serviced. Thanks in advance for any help!
