There may be a file on the card that the Fuze can’t read.Your computer is more flexible than the Fuze.
If it just started happening, take off whatever you added most recently. If you added all your music at once, Format the card (to FAT32) and add your music a few albums at a time. When you find what stopped it, fix it with mp3tag as explained here:
