A bad sector is like a scratch on a cd that can’t be fixed. You should run a program like "HD Tune", when you use a program what it does is it will read the disk and when it can’t read a certain spot it marks it as a bad sector. After that the hard drive will move the data from the bad sector to a spare area of the hard drive. The spare area will store the data from a bad sector and will be usable like the old one. However if you get too many bad sectors you will run out of spares.

Eassos PartitionGuru is a simple and freepartition manager software, which can be used to remove bad sectors from hard drive. It lets you fix hard drive partition wise or you can choose to scan all partitions at a time. All it does is confirm that the sector has gone bad (by repeatedly trying to write/read data on it), then instructs the hard drive to substitute a reserve sector in its place. From that point on, any time the computer requests that sector from the HDD, the HDD instead uses the reserve sector that’s been mapped into its place.
