I have just bought a 32gb Card for my Sansa fuze 8gb.
When I am filling the card with music the card allows me to copy the files over.
When In my computer I can see the sansa fuze and the Micro SD card with the music on.
When I turn my Sansa on only the a very small amount of music appears. However when i reconnect it back to my PC the music appears fine. Ive also tried this in a card reader and it all displays and plays ok/
Ive tried both USB Modes to no avail.
“When I turn my Sansa on only the a very small amount of music appears.”
Are you sure all of the music is in a format the player supports? The Fuze can’t play files in proprietary Apple formats. If your music is too deeply nested, ie. folders in folders in folders, etc. the player may not see it. Is your music properly tagged? If not, your player will be able to see the songs, but many songs will have the title and artist listed as unknown. The Fuze needs tags that are ID3v2.3 ISO 8859-1.
