    Disk Tools

    Scan Disk is one of the most common maintenance tools bundled with an operating system such as Windows. This is an application that is used in checking the hard drive of your computer for errors and bad sectors. Once Scan Disk finds an error in the hard drive, it will attempt to fix it.

    The errors found inside a hard drive are caused by a number of reasons. These include:

    • frequent system crashes
    • critical system applications that have been improperly closed
    • existence of harmful programs such as viruses, trojans, etc

    While Scan Disk is running, it will check the hard disk for defects in its platters (these are round flat steel plates in the hard drive on which data is stored). It will also check file systems (FAT, FAT32, NTFS etc). It will search as well as correct the lost and bad clusters that were created when a certain program was aborted.

    Once Scan Disk finishes its task, it will provide a report that contains the errors it has found and the amount of disk space it has scanned. It is therefore important for users to use the Scan Disk application because it ensures that their data is safe from being corrupted. Aside from this, there is a guarantee that their computer will perform at optimum performance levels.

    The earliest version of Scan Disk appeared in MS DOS 6.2. In Windows 95 and 98, Scan Disk was given a graphical user interface (GUI). In this graphical environment, the user can find:

    • progress bars
    • buttons
    • information regarding the status of the scan and the errors (if any)

    How to Run Scan Disk in Windows 2000 and Windows XP

    • Press the Start button on desktop
    • Double click on My Computer
    • Highlight the disk which you want to scan for bad sector on the list of Hard Disk Drives.
    • Open the File menu and select Properties option
    • Select the Tools tab
    • Click the Check Now button
    • The scannning process will then initiate

    How to Run Scan Disk in Windows Vista/7/8

    • Click on Computer in Windows Explorer
    • Right click the drive you want to scan with Scandisk and select Properties
    • Click on the Tools tab. Under the Error-checking sub heading, click the Check Now... button
    • A window named Check Local Disk will appear. If you want to attempt to correct errors, check the Scan for and attempt recovery of bad sectors checkbox
    • Click Start to initiate the disk scan. In Vista/7/8, it is required to schedule the Scandisk to make it run at boot time, as Vista/7/8 has mechanisms which do not allow it to run while the system is operating.

    As advanced as hard drives have become, one item they are not very good at is housekeeping, or maybe that should be drive keeping. When files are created, deleted, or modified it's almost a certainty they will become fragmented. Fragmented simply means the file is not stored in one place in its entirety, or what computer folks like to call a contiguous location. Different parts of the file are scattered across the hard disk in noncontiguous pieces. The more fragmented files there are on a drive, the more performance and reliability suffer as the drive heads have to search for all the pieces in different locations. The Disk Defragmenter Utility is designed to reorganize noncontiguous files into contiguous files and optimize their placement on the hard drive for increased reliability and performance.

    Disk Defragmenter is a computer program included in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique commonly known as defragmenting. The purpose is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate. As of Windows XP, Disk Defragmenter is also used to improve system startup times. To run Disk Defragmenter, simply follow steps above and you can find it under Tools tab.
