How to Run Scan Disk or Check Disk in Windows XP
Scan disk also known as Check disk for newer version of Windows. This tool is used to check if the hard drive has critical errors that might affect the performance of the programs installed in the computer. The errors in the hard drive can result into system crash such as blue screen, slow performance, user account corruption and corruption of files including personal files.
Scan Disk will check the hard disk for physical damages. It will also check damages on the software that is installed in it. The main purpose of scan disk is to look for bad sectors and restore them to working condition. This is due to improper termination of a running program.
Scan Disk will provide a report that contains the errors it has found and the amount of disk space it has scanned. It’s important to use scan disk to prevent your file from corruption. Aside from this, there is a good chance that your computer will perform at optimum performance level after it has been ran.
This is how you run scan disk or check disk:
1. Double click your My Computer icon. Right-click on the C: drive. Select Properties then choose the Tools tab .
2. Under Error Checking , click the Check Now button. A dialog box will pop up, check both check boxes and click Start .

NOTE: Some people say that when they try to run scan disk or check disk it keeps on resetting itself. It doesn’t happen all the time but if it happens to you there’s a way around this.
Restart your computer, just as your computer starts to boot up (before the Windows “splash screen” appears), keep hitting F8 on your keyboard. A menu should come up. Choose the SAFE MODE option then run Scan Disk following the normal procedure and it should work just fine. When done, re-set your computer and be sure to switch back to normal mode.
