Removing safely

How do I safely remove my Sansa Express? It shows up in my computer as “Sansa Express” but there is no way to safely remove hardware as it says to do in the manual.

In some programs (notably Rhapsody) there’s a disconnect feature.  Otherwise, once your file transfers are done, you can just pull the cord.  Since your computer isn’t mounting it like a disk, it doesn’t need to be told to unmount it before you unplug it.
