There've been many how-tos in fixing your broken iPod over the years, many of which recommend you to just reset and restore the iPod in hopes that it was a software corruption. If that doesn't fix it, Matt over at Crunchgear has a solution that's almost as easy.
All you need is to open up an iPod and shove a folded-up business card inside the case. The drive gets warm as it spins, which in turn warps the case and renders the drive inoperable. By shoving the card in, you're securing the disk and ensuring that you can rock out to Echo and/or his bunnymen once again.
