Check Disk (CHKDSK) in Windows 10: Syntax, Parameters, Examples

-

|

Introduction

Check Disk (CHKDSK) is a Windows 10 command tool that checks a disk for errors, fixes errors, recovers bad sectors and displays a status report.

This guide covers how to run check Disk (CHKDSK Syntax), parameters of CHKDSK and examples.

Some people refer to CHKDSK as simply Check Disk. That is okay for reference purposes only. It is important to note that the actual command in Windows 10 (and previous versions of Windows) is CHKDSK.

How to Run Check Disk in Windows 10 (CHKDSK Syntax)

Below is the syntax of the CHKDSK command:

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B] [/scan] [/spotfix]

The actual parameter you use in the above Syntax will depend on what you want CHKDSK to do. In the next section, I will explain what each parameter means and explain what they do.

CHKDSK Parameters Explained

The table below lists the parameters of CHKDSK and, what each parameter means and how to use them.

3/FFixes errors on the specified disk.
4/VIf /V swicth is used on a FAT/FAT32 partition, it displays the full path and name of every file on the disk. On NTFS partition, /V Displays cleanup messages if any.

6/L:size*/L:size changes the log file size to the specified number of kilobytes . If size is not specified, displays current size.
7/XForces the volume to dismount first if necessary. All opened handles to the volume would then be invalid (implies /F).
