What does Check Disk Utility do?
Check Disk is a tool that verifies your disks for file system integrity, locates bad sectors and recovers readable information. This can be very helpful when you have some form of hardware failure which affects the integrity of your files. Unless you have some serious hardware problems, Check Disk can help you recover corrupted information from your hard disk, floppy disk or memory stick.
Check disk works by checking the sectors, indexes, and some other things on a drive and rearranging anything that's in the wrong place. If you run check disk on a fairly routine basis, you're likely to notice an increase in your hard drive's performance.
