i dont put it in folders. i just copy them all in one place. is that the reason why the player is having a hard time reading some of my memory card's content? i have all my music in that 64gig, i think i have to divide them by folders so that the player could read it easily that way. ill try it. thnaks. i left 150mb free. i tried copying them back again, but then, after long wait of reading the card by the dx90, it still showed no artist under T, U, V, W, X, Y and Z. and some of the artist under S name is still missing. (just like SARA BAREILLES etc) im really sure i edited them all by itunes, so mp3 tagging is no problem and the dx90 wont have problem organising them alphabetically. to answer your question, yes, i did copy them in my memory card, along with the other artists. and the dx90 stopped at letter T. some artists just cant be found. ill try deleting the memory card's content again. ill try transfering all the artists back again by perhaps putting them all into at least 5 folders. i only put them in the base folder all (perhaps the mp3s number are in 3,000 songs all in all) im having a theory that the dx is having a hard time reading it all in one location. i also tried today deleting the current lurker firmware, formatting, and installing back the firmware. after rescanning, its still like that again.
