In a Windows PowerShell program, parameters are additional commands added to the end of the program name, with characters before each parameter.Read more April 17, 2020 CHKDSK (pronounced Check Disk) is a very useful and vital tool for monitoring your disk drive health.This tool uses a multipass scan of a drive to verify that its soundness and functionality are intact.
Using CHKDSK to ensure your drives are running correctly is a great way to speed up Windows 10, and we suggest you use the tool every few months to keep your drives safe and healthy. In this article, well go over what CHKDSK is, how it works, and how you can use it to repair your hard drive in Windows 10. How CHKDSK Works CHKDSK starts by scanning the file system on the disk drive and analyzing the integrity of the files, file system, and file metadata on the drive. When CHKDSK finds logical file system errors, it fixes them in place, saving the data that is on the disk so that nothing is lost. Logical file system errors are things like corrupted entries in the drives master file table (MFT), a table that tells the drive how files are connected in the murky labyrinths of the drives hardware. CHKDSK also fixes misaligned time stamps, file size data, and security flags on files on the drive. CHKDSK can then conduct a complete scan of the drive, accessing and testing every sector of the hardware. Hard drives are divided into logical sectors, defined areas of the drive where a certain defined quantity of data will be stored. Sectors can develop soft errors, in which case data has been written incorrectly to the magnetic medium, or hard errors, which are cases when the drive itself has an actual physical defect in the area designated as a sector. CHKDSK fixes soft errors by rewriting the faulty data and resolves hard errors by marking that section of the disk as being damaged and out of bounds for future use. Because CHKDSK has been updated and upgraded repeatedly with each new generation of storage hardware, the program continues to work correctly to analyze and repair hard drives of any sort. The same process that used to be executed to analyze a floppy disk holding 160K, can today be executed to analyze an SSD holding 15 terabytes. Running CHKDSK on Windows 10 Although there are several different ways that you can invoke CHKDSK on a Windows 10 machine, by far the most common and ordinary place to run the utility is via a command prompt known as the Windows PowerShell. However, because CHKDSK talks directly to drive hardware, it requires a special level of operating system permission known as administrative privileges. This just means that CHKDSK is allowed to run as though it was the account that is in charge of the computer. This brings up the power users menu in the start menu area, where you will see several options. You can release the Windows Key X combination and type the A key (short for Admin) to launch the Windows PowerShell in administrative privilege mode. ![]() The next screen to appear is a User Account Control (UAC) window which will ask for permission to launch the Windows Command Processor and let it make changes to the PC. Select Yes. The Windows PowerShell will now launch a familiar black and white box with a text command-line interface. The most basic way to invoke CHKDSK is simply to type the name of the program chkdsk, followed by a space, then the letter of the drive you wish to examine or repair. In our case, its internal drive C:, so the command would be chkdsk c: This basic invocation of CHKDSK will scan the disk and display status information, but it will not fix any errors that are encountered. To run CHKDSK in a mode where it will actually fix problems that it encounters, you need to add several parameters.
