If the 80 gigabyte hard drive that came with your MacBook is starting to feel cramped, there's good news.

The following picture isn't it.

And I have no idea why it's there.

Still, the guys over in instructables.com have published a full guide as to how to back up your MacBook's hard drive, where to acquire materials, how to clone your data for backup purposes, what tools you'll need and how to dig into your MacBook to replace the internal hard drive.

Take a gander and if you've found a good shortcut or workaround to help the upgrade process, let us know over in the comments or forums.
