Jay100

After i transfer my songs mp3 to atrac on the nwa 1200 i find that only about half of them can be played I keep getting the error message that the music file is damaged some tracks from the same cd play others don't this is really strange any help would be appreciated thanks

thanks I just got my sony NW A1200 and am goin on a 8 hour long trip I plan of listening to mostly audio books and some music that thing is great except for the volume wich is ok but not so loud even after unlocking it, I'm experimenting with the equalizer controls at the moment.

Can any one tell me wich file format atrac vs mp3 gives a better battery life on the sony walkman NW A1200 ? thanks
