Sorry to hear that, some of the MP4 player manufacturers are making really bad MP4 players, mainly the ipod nano clones, they are basically formatting 256/512mb memory to look like they hold more. If you try to format the player, you will end up with the actual amount of memory.

There is nothing you can do to fix the player all you can do is try and get a new one from the person you bought it from (if possible).
