How to Fix Bad Sectors on a Hard Diskby C. Taylor
Bad sectors can crop up on a hard drive from excessive heat, physical abuse or simply extended use. Even new drives can have bad sectors.

This correction simply bypasses the bad sector, so the system doesn't use it, but at the same time, data residing in a bad sector is patched and moved to a healthy area of the drive.
Click "Start" and select "Computer" to open Windows Explorer.
Right-click a drive letter and select "Properties."
Click the "Tools" tab and click "Check Now" in the Error-Checking section.
Check "Automatically Fix File System Errors" and "Scan for and Attempt Recovery of Bad Sectors." The latter selection is a more thorough but lengthier process.
