ExtremeTech have thrown up a guide for modifying your nomad MP3 player by adding a bigger hard drive! What they're about to show you WILL void your warranty, so before proceeding, make sure you understand once you start, you're leaving your warranty behind. Here's a byte: OK, call us curious. Call us dumb. Call us adventurous. Whatever, we decided to see if we could replace the hard drive in our Zen, and our Nomad Jukebox 3 to add more space for more music. And guess what? It worked. In this story we'll give you the details on what we learned, and pictures and instructions on how to do it yourself. This is not for the squeamish, but it is possible to add a bigger hard drive to your MP3 player.
