Detect and Repair Disk Errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.

If you use your computer daily, you should try to run this utility weekly to help prevent data loss.

Important: Be sure to close all files before running the Error-Checking utility.

To run the Error Checking utility:

1. Click Start, and then click My Computer.
2. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
3. In the Properties dialog box, click the 'Tools' tab.
4. Click the 'Check Now' button.
5. The 'Check Disk dialog box will pop-up. In that dialog box, check the "Scan for and attempt recovery of bad sectors" box, and then click on Start.
6. If bad sectors are found, choose to fix them.

Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.

Bad sectors really slow down the hard drive. The tool you shared will help to inspect the hard drive, i will check it.
