A few days ago I bought a Sansa Clip +. I tried to add some audio files on my microSDHC card. Although the files have transferred successfully, but some files disappear, and memory card space is still occupied.
There is some exaple:
(2009-08-14) (C76) EXIT TUNES - EXIT TRANCE PRESENTS ウマウマできるトランスを作ってみた COMPLETE BEST/Do-Dai.mp3
 茅原実里 - D-Formation(320K)/11.TERMINATED.mp3
How to solve this problem?
Can someone help me?
Thanks in advance.
