Great, thanks for the advice. When doing diary entries, track marks are added each time I make an entry and I'd like to preserve those. It would be horrendous to have to put them back in.
I'm curious whether the track marks are copied when transferring old format MDs to computer for reformatting to CD or MP3. I've made audio diaries for years. First on cassette and later MDs. I'd like to make back ups of these but need the track marks.
