Check Settings->System Settings->USB Mode
There are two modes of USB operation: MSC and MTP. Plus there’s an Auto mode.
MSC makes the Fuze look like a memory stick.
MTP stands for Media Transfer Protocol, a Micro$oft developed protocol for connecting media players to a host computer.
The Fuze’s Auto mode defaults to MTP, but falls back to MSC if the host computer does not have drivers for MTP. Mostly it’s best to choose MTP or MSC, then you know how your Fuze is connecting.
The relevance of all this is that the Fuze stores items transfered by MTP in one area, and by MSC in a different area. The host computer can only ‘see’ the storage area for the mode in which it is connected. The Fuze always sees both areas.
The Fuze’s included content is stored in the MTP area, so it sounds like your host computer is connected in MSC mode.
If you’ve got a Windows PC, you need at least XP SP2 and at least WMP 10 to get the MTP drivers.
MSC mode is generally a bit more reliable, but you need MTP if you have content that has DRM attached.
