[brignuca]

Thank tadad1 for bbeing so patient but I can't apply your suggest. I have tryied with 3.68 mp3 disk utilities. The result is that I can see a disk with a capacity of 1951.74Mb but when I try the format (every option) the resule is "not supporting this disk type. Now I've tried a format from the system in fat32 and the proble looks solved, I can't understand why but it's solved. Now I have some other players to look at. Probably I'm going to ask your help another time in the next days
bye
