CHKDSK, or Check Disk, is a valuable Windows utility designed to help maintain the health and efficiency of your computer by checking for file system errors, bad sectors, and other common disk issues.
Whether your computer is acting up with crashes, slow performance, or corrupted files, running CHKDSK can often provide a solution.
This guide explains how to use CHKDSK in various ways, including through File Explorer for a quick check, using the Command Prompt for a detailed scan, or from installation media if your PC fails to boot.
Each method is tailored to different scenarios, ensuring you can keep your system running smoothly under various conditions.
What is CHKDSK?
CHKDSK is a tool in Windows that helps you find and fix errors on your computer. It checks files and their details on the disk to make sure everything matches up and looks for any damaged parts of the hard drive that could cause problems with your data.
You can use CHKDSK to check for these errors in Windows 10 or 11, especially when files are not stored correctly.
When is the Right Time to Run a CHKDSK?
- Computer Crashes or Freezes: If your computer often stops working or shuts down unexpectedly, CHKDSK can check for disk issues and fix them.
- Slow Computer: If your computer is slow, especially when opening files or programs, CHKDSK can help by fixing disk errors.
- Corrupted Files: If your files start to get corrupted or you can’t open them, running CHKDSK can help find and fix the problem.
- Noisy Hard Drive: Your hard drive may be having issues that CHKDSK can resolve if you hear clicking or grinding noises coming from it.
- Disk Error Messages: When your computer warns you about disk errors or bad sectors, use CHKDSK to repair these before they get worse.
- After a Virus: If your system had a virus, run CHKDSK afterwards to fix any damage the virus may have caused to your files.
- System Instability: If your computer often restarts on its own or crashes, CHKDSK can check your hard drive and files to make sure everything is okay.
How to run CHKDSK on Windows?
CHKDSK (check disk) can be used in three different ways to examine your hard drive, external drives, and any SSDs you may have.
It’s easy to run CHKDSK on Windows 11, and the instructions won’t be all that different from those for Windows 10. This utility has been in use for decades, guaranteeing that your computer operates as it should throughout multiple Windows versions.
Method 1: Running CHKDSK Through File Explorer
Step 1. Open File Explorer: Click on ‘This PC’.
Step 2. Look for Errors: Go to the ‘Tools’ tab and press ‘Check’.
Step 3. Decide to Scan: If it says “You don’t need to scan this drive,” but you want to check anyway, click ‘Scan drive’.
Step 4. Check Results or Finish: After scanning, click ‘Show Details’ to see any fixed errors, or ‘Close’ to exit.
This feature in File Explorer is a user-friendly version of CHKDSK. It allows you to check and repair disk errors without using Command Prompt. If this quick check finds no problems, there’s usually no need to run additional CHKDSK commands through Command Prompt.
Method 2: Run CHKDSK from Installation Media
If your PC won’t start or shows a “Blue Screen of Death,” you can run CHKDSK using a USB or other bootable media with Windows installed.
This method helps check and fix errors before Windows starts. It’s also useful if you can’t run CHKDSK normally due to errors like “volume in use” or “access denied.”
Steps to Run CHKDSK from Bootable Media:
Step 1. Insert Bootable Media: Put your Windows CD, DVD, or USB into the PC and restart it.
Step 2. Access Boot Menu: Press the F8 key repeatedly before the Windows logo shows up to get to the boot menu.
Step 3. Computer Repair: Select ‘Repair your computer’ from the menu.
Step 4. Go to Troubleshoot: Click ‘Troubleshoot’, then ‘Advanced options’.
Step 5. Choose ‘Command Prompt’ from the list of alternatives to launch Command Prompt.
Step 6. Identify Your Home Drive:
Type c: and press Enter. Type dir and hit Enter to see the directory’s contents.
- If you see Windows files, that’s your home drive. If not, repeat with other drives (d: e: etc.) until you find the correct one.
Step 7. Enter the commands for CHKDSK: Enter the CHKDSK command on the Command Prompt now.
Step 8. Schedule CHKDSK if Needed: If asked to run CHKDSK on the next restart, type Y and press Enter to confirm.
Method 3: Run CHKDSK from the Command Prompt in Windows
- Open Command Prompt as Administrator: Search for ‘cmd’ in the Start menu search bar, then select ‘Run as administrator’.
- Run CHKDSK Command: Type ‘chkdsk’ and press Enter. This will scan your drive for errors and report any issues found, but it won’t fix them unless you specify further commands.
These steps apply to all versions of Windows, including Windows 11 and Windows 7, allowing you to tell your computer to check for disk errors and report them.
Conclusion
Using CHKDSK is essential for keeping your Windows computer running smoothly. You can easily run it through File Explorer for quick checks, Command Prompt for a thorough analysis, or from a USB if your computer won’t start.
Regularly using CHKDSK helps prevent serious problems, keeps your system stable, and ensures your computer lasts longer. This small action can prevent more serious problems later on.
