How do I replace the hard drive in my full-size iPod model or iPod mini?

If your iPod is no longer under the one year warranty period, Apple's repair prices are prohibitively expensive, practically the cost of a new iPod.

However, if you have effectively determined that the hard drive in your iPod or iPod mini needs to be replaced, and you are technically inclined, self-replacement is difficult, but entirely possible. As the hard drive in the "full size" iPod and iPod mini models is not attached with adhesive, replacing the hard drive is generally easier than replacing the battery in some models.

iFixit provides manuals that can be used to replace the hard drive in the full-size iPod models as well as the iPod mini.

Site sponsor Other World Computing provides videos to replace the battery in many iPods and the videos for the iPod 3G and 4G in particular can be used to upgrade the hard drive as well. This video covers the iPod 4G:
