Find and Repair Hard Drive Errors With Windows CHKDSK

CHDSK is a handy tool included with Windows XP, Windows Vista, Window 7, Windows 8x and Windows 10, that you can use to check your hard drives for errors. Most of the time CHKDSK can also fix the errors it finds.

You should run CHKDSK every two or three months to check the integrity of your hard drive(s) and to fix any errors you may have. The average life span of a hard drive varies — but we’ve found that once a hard drive is five or six years old, they start to fail – but there is no standard hard drive life. We use our computers more heavily than most users – so with lighter use a hard drive may last longer.

But, there’s more to running CHKDSK than running it in the default mode. By using “switches” you can run CHKDSK like a pro, even if you’re not. Amaze your friends with your knowledge! It’s easy. We’ll show you how to use Scan Disk and show you a few switches you can use when running CHKDSK (and a little explanation of what each switch does):

Let’s Check Our Hard Drive(s):

  • Double click on My Computer
  • Right click on the drive you want to check
  • Select Properties
  • Click on the Tools tab
  • Click the “Check Now” button
  • Select “Automatically fix file system errors”
    Note: this is the same as running CHKDSK /f.
  • Select (if desired) “Scan for and attempt recovery of bad sectors”
    This is the same as using the switch CHKDSK /R. this scan takes a long time – so be prepared
  • Reboot if necessary

You can also run CHKDSK from the command line (Run) which will give you even more options. Click “Start” then “Run”  then type CMD . When the DOS-like window appears, type in one of the following commands at the prompt (the flashing cursor). Be sure you leave a space after CHKDSK (before the slash) or it won’t work.

Here are some of the “switches” available. If you’re currently running Windows and you’re attempting to run CHKDSK on the Windows drive you’ll get a message that the volume (drive) is currently in use. You’ll be asked if you want to run CHKDSK the next time you start Windows. If that’s what you want to do (and it normally is, type “Y” without the quotes).

CHKDSK /F (Run CHKDSK and fix any errors)
CHKDSK /R (Run CHKDSK and identify bad sectors)
CHKDSK /V (Run CHKDSK on FAT32 drives and display a verbose (wordy) output
CHKDSK /I (Run CHKDSK on NTFS drives and display a verbose output)
CHKDSK /C (Run CHKDSK and skip the checking of cycles within folder structures)

    What I have always been unsure of when talking about CHKDSK is whether you must have an istallation CD in the drive when running it to correct errors.

      You’re confusing CHKDSK with SFC (System File Checker). There is no benefit in putting the installation disk in while running CHKDSK.

      And regarding SFC, those using Windows Vista and newer versions of Windows, the installation disk is not needed and does nothing. Only Windows XP required the installation disk. Newer versions of Windows contain backupt copies of essential system files.

    I note the reference to Hard Drives. Is this application safe to use on SSD’s?

    I normally put the installation CD in the drive,so that CHKDSK has access to any missing or corrupt files. I am not sure if this is absolutely necessary, but I believe I read in a computer magazine (a long time ago) that this is the proper thing to do.

    Thank you for this clarification on both CHKDSK and SFC and the different operating systems . I had read your article from Aug 3, 2011 but didn’t find any references to Vista (and forward) to not having to use an installation, but got the opposite impression. Thanks again.

    Can you run CHKDSK if you are using windows mail or will it foul up the settings for windows mail?
