This video tutorial shows you the inside components of a hard drive and how they work together. I go into great detail on self diagnosing your hard drive. If your drive appears to be failing (i.e. your PC can't read from the drive) or it doesn't appear to turn on, this tutorial will help you to diagnosis what the problem may be. This video is great for anyone looking to understand how a hard drive works and the components that make up a hard drive.
