Running CHKDSK on Windows 10Īlthough 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 Windows PowerShell, the intended replacement for Windows Command Prompt. The exact process used to analyze a floppy disk holding 160K can today be executed to analyze an SSD holding 15 terabytes. CHKDSK fixes soft errors by rewriting the erroneous data and resolves hard errors by marking that disk section as being damaged and “out of bounds” for future use.īecause 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 and SSDs. They can also get “ hard errors” when the drive has an actual physical defect in the area designated as a sector. Sectors can develop “ soft errors,” in which data has been miswritten to the magnetic medium. Hard drives are divided into logical sectors, defined areas where a certain quantity of data will be stored. CHKDSK can conduct a complete disk drive scan, accessing and testing every hardware sector. Logical file system errors include several things, such as corrupted entries in the drive’s master file table (MFT)-a table that tells the drive how files are connected in the murky labyrinths of the drive’s hardware.ĬHKDSK also fixes misaligned time stamps, file size data, and security flags on HDD files. 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. How Windows CHKDSK WorksĬHKDSK starts by scanning the file system on the HDD/SSD and analyzing the integrity of the files, file system, and file metadata on the drive. This article explains the details of CHKDSK, how it works, and how you can use it to repair your hard drive in Windows 10. Using CHKDSK to ensure your HDDs and SSDs 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. This tool uses multipass scan activity to verify that a drive’s health and functionality are intact. If you can't find what you need, please Google your drive manufacturer name and add something to your search like drive tools.CHKDSK (often pronounced “Check Disk”) is a handy and vital tool for monitoring your HDD or SSD health.

Some companies offer SSD specific apps you can browse here. We have some of these apps on MajorGeeks including Samsung, Seagate, Western Digital, and Maxtor. While we can use Windows utilities to check for problems, we'd use your drive manufacturer tools. We'd try Crystal DiskInfo.Īll companies offer dedicated tools to help you manage, monitor, and repair your drives. You might want to use CheckDisk or possibly System File Checker. Keep in mind that the Windows SMART health report has never been perfect. If a problem is found, you can get more details by checking the SMART Predict Failure results. If you do receive errors, stop everything, and back up your hard drive immediately before its too late. Any problems found with your drive will be explained, and you will need to consider whether you need to repair or replace your hard drive.

WMI will query your drive to get SMART information from your drive. Open a Command Prompt or PowerShell and type in wmic.

In this guide, we show you how you can use WMIC to test your hard drive health quickly.īefore we run this simple test, be sure to close all running programs and save your work. WMIC extends WMI for operation from several command-line interfaces and through batch scripts. Windows Management Instrumentation or WMI is a lesser-known powerful utility that comes with Windows 10, 8, and 7.
