As a fairly new (December 2007, Express) Sansa user, I read the threads in the forums on occasion. Upon finding out that the lastest firmware update can handle a 4GB microSD card, I picked one up yesterday (of course, it is a SanDisk).
After a FAT32 format, I put it into my Express. Windows Media Player 11 recognized it straightaway with “Internal Memory” and Expansion Card" listed. Thinking that things were okay, I went ahead and put songs on the card-- about 3.5GB worth.
Here’s where it gets interesting: After powering up, the Express displays “No Song” when I select “Play All”-- even though I know I put over 750 songs on the card. the “System Info” on the SE says that the requiste amount of space has been used up on the card…but no songs. Hopefully someone here can help me fix this problem. Many thanks…
