Hi! Hope someone might know a way to... I recorded a concert and halfway through I changed the battery. Afterwards, I found I only had the first track. The second one didn't show up, however I had looked at it during the concert and the second track had been recording for at least 45 minutes. I had been jumping around during the second track recording and the second battery was a cheaper one that is a little bit shorter than a proper one. I think what has happened is the battery lost contact with the terminals during recording the second track and lost power, and hence the TOC didn't get updated (so the TOC thinks there's only one track). Then I realised that the data itself must be on the disc, just that the TOC doesn't know it's there. Does anyone know if there is a way I can get this data? Maybe just to play all 74m59s straight through or something? Even just once so I can record it into my computer. Thanks!
