You will have problems totally trashing it.

The memory which holds the "re-flasher" code is hardware write protected - you can't trash this without opening up the player physically and shorting things. This means that in the worst case, applying an upgrade file will cure your player whatever state it's in.

This *doesn't* mean you can't trash your disk and all the music, though... you can't toast the flash to a point of no return though.
