I recently bought a 8gb microSDHC for my 4gb Sansa Fuze.
My problem is, that the card appears empty when viewed on the player, though I know it isn’t. An update to Firmware Version V01.02.31F did not help.
When I plug the player in my pc, the tracks on the memory card can be seen, but when accessing the memcard on the player via music > folders, the memcard looks empty.
The card is FAT32 formatted.
