Hello! It is very important to ensure the integrity of the hard disk in the computer. Since it is an essential element for the system. Indeed, the failure of this element will cause instability, expenses and loss of information. Consequently, it is important to watch over the integrity and performance of this hardware. Certainly there are third party apps that do this function. However, Microsoft included its own tool to detect and correct errors in the hard disk. This is the CHKDSK command. This is a very useful Windows command for the health of the system in general. Well, today we will see how to use the CHKDSK command in Windows 10.

What is CHKDSK?

It is a command that analyzes, repairs and checks the state of the hard disk. It also aims to improve the performance, use and speed of the disk. In addrion, it provides the following options:

  • Scanning, repairing and solving the physical problems presented by the hard disks in the system.
  • Real-time hard drive integrity check
  • Repair of logic errors.

How to check the hard disk with the CHKDSK command

As mentioned, when we use the command alone, a report is displayed. Now, to execute actions, you have to use this syntax:

Below I show you some commands and their usefulness:

chkdsk /scan

Scans and searches for errors on an NTFS disk

chkdsk /spotfix

This command will instantly unmount the volume to fix problems that were sent to the registry in previous analyses:

chkdsk sdccleanup

This command can only be used on NTFS systems. In effect, it will collect and then delete data that the analyzer does not use. Additionally, it includes the use of the /F parameter.

chkdsk offlinescanandfix

It can only be used with NTFS disks and must be used in conjunction with the /scan command. This command performs an online scan and sends errors to a queue for offline repair.

chkdsk /scan /perf

It is only for use on NTFS disks and must be used with the /scan command. Additionally, It allows you to use more system resources to perform a scan as soon as possible. However, it may produce a slower system state.
