Just got a 16GB SD card (SanDisk) for my Fuze 8GB. Synced a bunch of albums (over 13GB) using Windows Media player. Some random albums are visible on the SD card when viewed through WM, but when disconnected they can’t be found on the Fuze, by album, artist, genre, nothing. Tried re-syncing, WM says they’re already present on player. Deleted one, synced to the internal memory, and it shows up. All files are mp3, all appear to have good tags as there is album art and titles. Help!
