I just bought a 4GB Fuze with an 8GB memory card. All my songs show up fine on the device, but when I plug it in to the PC only half the song files are in the internal memory. The SD is empty so I don’t think that’s the issue (tried removing the card, no change).
Also, mp4s that I add to the video folder don’t show up on my Fuze at all. Don’t know if it’s related.
P.S. If it helps, only MSC mode works, and I have Windows XP SP3.
