I put a T-Mark at the 14:00 minute mark of a recording, then realized that I needed a t-mark to be before then. So I set my second T-Mark at the 12:00 minute mark. Since then I have been getting a read err. I tried other discs and they work fine. I am assuming that t-marking my second track before the 1st is what messed things up. Is there any way of resolving this to get my audio from this disc. I have a wedding ceremony on it and am pulling my hair out. I seem to get a read err with whatever functions I attempt to perform with this disc. Thanks. (MZ-N707)
