Disk scan always starts when you turn off your computer in a hurry. It can be a system crash or simply power cut. The scan disk scans your hard disk for bad sector. It is always suggested that you turn off your computer properly by the recommended method.





Always check out battery of ups (uninterrupted power supply). Still, you must scan your hard disk once a week. Open you’re my computer and right click on a drive. Then go to the properties.



There you will find a disk cleanup option. This option is used to cleanup your disk by deleting unwanted files. You can recover some hard disk space by doing this.




After that, click on the top tab that says, tools.



In the tools tab, you can click on the disk scan and the defragment. It is recommended that you first do the disk scan, and then defragment the drives.



We will discuss the de-fragmenting drives in the later posts.
