This article is a continuation of the previous article that discusses about How to Fix Hard Disk Damage using Checkdisk. In this article I will discuss about how to fix a damaged hard disk due to bad sectors. Previously, to check the condition of the hard disk we can use several application programs as mentioned in the article on How to Fix Hard Disk Damage using Checkdisk.

Bad sectors or bad blocks is a term used to refer to damaged area on the hard disk. There are two types of Bad Sectors on hard disk in general, physical bad sectors and bad sectors in the software. Physical Bad sectors occurs because of damage to the hard disk plate that can occur due to disk exposed to dust, falling, hard impact, or other reasons. While the bad sectors in software may occur when the hard disk is on working, but suddenly the computer is turned off, for example due to power failure.

With hardisk tool utility like HD Tune, we can do Error Scan to find bad sector on hardisk.

There are several applications that can be used to repair damage caused by the hard disk bad sectors, including the following:
