How to Fix a Corrupted Hard Drive
If your hard drive is corrupted, you will need to correct the problem in order to restore your computer to full functionality. In Windows, hardware corruption can occur due to bad exits, such as power failure. Windows includes native functionality to correct data corruption on hard drives.
