You have a "hacked" player, it isn't 2GB worth of memory, its probably a lot less, its just been formatted to look like it can hold 2GB.

There is a slim chance that it might be a firmware option, look through the forum for support.

I would also recommend you contact the person you bought it from and look for a exchange or refund (i would recommend doing this before you go forth and change the firmware or format the player).
