Can't Read SD Card Anymore / Can't Turn It On?!

  1.  Are you aware of the 2000 audio file limit (for internal memory and SD card memory) with FirmWare 1.27 and 1.29?

.  

 2  Maybe your MUSIC.LIB file is corrupted?  You should always use the Eject Command to allow the Clip Sport to properly compile the MUSIC.LIB file after each audio file copying session.  If nothing seems to make this work. Try deleting the MUSIC.LIB file from your SD card.
