You can check and remove the errors from your system's hard disk by using built-in tool. By removing hard disk errors, you can solve some computer problems and also improve the performance of your computer. You need to follow these steps to check and remove errors from your system's hard disk:
1. Open My Computer by clicking the "Start -> Computer" menu button.
2. Right-click the hard disk drive that you want to check, and then click Properties.
3. Click the Tools tab, and then, under Error-checking, click Check Now.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.
To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
4. Click "Start" button to start the error check.
This process may take several minutes depending upon the size of your system's hard disk. For best results, don't use your computer for any other tasks while it's checking for errors.
