Josh Highland provides a great step-by-step tutorial demonstrating how to replace the drive of an iPod. Following the steps proved little trouble, allowing me to fix my mother-in-law’s hard drive after the iPod started misbehaving. As the new hard drive is much cheaper than the cost of a new iPod, and as Apple would have only given her $25 to trade it in, the choice was easily made. 30 minutes and a bit over a hundred bucks later, Linda has a working iPod.
