Is your hard drive making loud noises and various error messages pop up when you start up and shut down your computer? Hard drive bad sectors are the most likely cause for these errors.  Bad sectors are not uncommon and most systems have them without suffering any performance drops.

Fortunately, it’s possible to fix some bad sectors and prevent the appearance of new ones. Here are a few tips that will help you.
