ive heard something about msc mode but i dont know how to do it can anyone tell me what im doing wrong? 

What’s your system and software?  MTP USB mode requires at least Windows XP with SP2, and Windows Media Player 10.

For MSC USB mode:  Settings/USB/MSC, if you have a more recent firmware; or put the hold switch on and hold the center button down while connecting the USB cable between Clip and computer.  (And then upgrade to the latest firmware–see the sticky thread at the top of the forum–so that you can set the MSC mode.)
