I have a Sansa Clip + 2Gb. And i have one microSDHC 8Gb inside (FAT32).
I try to play some FLAC files, It’s work on the internal memory of the sandisk, but when i tried to put the same folder on the memory card. I use the view “Folders” for playing music.
The sansa shows “Empty”.
Its a bit strange. Each files are encoded with the last version of flac codec in level-0.
