Hi, I'm just wondering if anyone's heard of or experienced minidiscs 'corrupting' over time? Because I've transferred loads of songs to certain minidiscs and they all played fine, but then over the past few weeks or so, i've noticed that my player had been missing a tiny bit off the end of tracks, not a LOT, but a noticeable chunk, say, 5 seconds? And a few tracks actually disappeared, like, when played, the tracks were just silent for 4 minutes or however long the song was. Could this be minidisc corruption or just something to do with a low battery or something?
