How to fix a bad sector on hard drive

What is bad sector

A portion of a disk that cannot be used because it is flawed. The operating system identifies any bad sectors on the disk and marks them so they will not be used when you format it. If a sector that already contains data becomes damaged, you will need special software to recover the data.

It’s not unusual for a hard disk to leave the manufacturing process with a damaged sector; however, this does not affect the overall performance of the disk as the damaged space is considered unusable.



How to fix it

On Windows XP, you can start with a "chkdsk /R". (/R: "Locates bad sectors and recovers readable information"). Fire up a command prompt to run that command.

Under Windows 9x, (95, 98 and Me) I believe scandisk has an option to do a surface scan and repair as well.

You can check "SpinRite" available at Gibson Research.

If the problem cannot fix why don`t you buy a new one hard disk :D
