How often have you noticed the chugging or grinding noises from your computer? Do warning messages about failure to save your work on your data disk pop up on your screen from time to time? If they do, probably you will need to look into fixing the ‘bad sectors’ in your computer. Bad sectors are portions of the computer’s hard drive that are damaged and no longer have the ability to save or store your data. The common causes for bad sectors are magnetic disc failure or internal physical damage. You can repair the bad sectors in your hard disk, in case you are using a Windows Operating System, by running an auto-error check on your system and initiating the repair process. Here’s a step by step procedure on how to repair a ‘bad sector’ in Windows 7 hard drive:

Select ‘Computer’ from the Start Menu
On opening the Start Menu, you will find an icon saying ‘Computer’ in Windows 7 and ‘My Computer’ in Windows XP. Select the ‘Computer’ icon and open it.
Select the Properties tab of the affected drive
After opening the Computer tab, your screen will list out the drives in your computer. Select the affected drive, use the right click of your mouse to open a floating menu. At the end of the floating menu, you will find the properties tab.
