CHKDSK.cmd to repair the disk

Check Disk (in short: CHKDSK) is a built-in Windows tool that looks for damaged files or bad sectors on the hard disk and prepares a report. If it finds an error, it sends a message: "Restart your computer to repair the file system" and repairs them if required.

Quick Tip: Use this tool if your computer is slow, barely disk space left, or suspect that on hard drive occurred errors.

Can CHKDSK be run on SSD?

Running CHKDSK on both SSD and HDD is safe.

Let's begin:

There are three ways to start the Windows Disk Checker tool. The first two options are manual startup, the third option is to automatically run the CHKDSK.cmd file, which can be downloaded from the link below:

A.) – Manual launch from the Search box:

(1) Type the CHKDSK command in the search field on the taskbar, and then press the Enter key on your keyboard.

(2) In the window that appears, click the Run as administrator link.

(3) The disk check command line will start immediately, where you can see the process.

If it finds an error, follow the on-screen instructions. If no errors are found, the command line window closes automatically at the end of the operation

Run as administrator

B.) – Manual start from File Manager:

To get started, open a new File Manager window. Press the Windows-Logo and E key on your keyboard at the same time, then click the This PC icon on the left side of the window (if the icon is not visible, scroll down).

C.) – Start Disk Checker automatically:

If you skip the manual operation described above, use the command file, which starts with just one click, which can be downloaded from the link below. The disk checker CHKDSK.cmd doesn't run any faster either, it just starts the same program with a mouse click.

You can download it as a ZIP compressed file by clicking the link below, then it needs to be unzipped (eg on: Desktop).

Important: The file must be run as administrator. Right-click the downloaded and then unzipped command file "CHKDSK.cmd", and in the small mouse menu window that appears, click the Run as administrator link with left mouse button.

Quick tip: Depending on the number of files, the size of the hard drive, and the number of errors that occur on the hard drive, the CHKDSK process can take several minutes or hours.


Note: Disk Checker locks the hard drive during this operation and does not allow other programs to run until it is finished. It's important to run when you know you won't be using your computer for a few hours.

Warning: Do not interrupt CHKDSK while it is running unless the program stops responding or displays an error message. Interrupting CHKDSK requires a system restart and may result in additional errors.

Attention: Improper handling can lead to an error, so it is recommended to create a restore point from which the original state can be restored.
