Fix Hard Drive Errors Cmd – CHKDSK (pronounced “Check Disk”) is a useful and important tool for monitoring the health of your disk. This tool uses a multi-pass scan of the drive to check that its health and functionality are intact. Using CHKDSK to make sure your drives are working properly is a great way to speed up Windows 10, and we recommend using the tool every few months to keep your drives safe and healthy.
In this article, we’ll discuss what CHKDSK is, how it works, and how you can use it to repair your hard drive in Windows 10.

CHKDSK starts by scanning the disk’s file system and analyzing the integrity of the disk’s files, file system, and file metadata.

If CHKDSK detects logical errors in the file system, it fixes them in place and saves the data to disk so that nothing is lost. Logical file system errors are things like corrupt entries in the disk’s Master File Table (MFT), the table that tells the disk how files are related in the murky maze of disk hardware.
CHKDSK also fixes invalid time stamps, file size data, and security flags on disk files. CHKDSK can then perform a full disk scan, accessing and checking each hardware sector. Hard drives are divided into logical sectors, defined areas of the disk where a certain amount of data is stored.
Sectors can produce soft errors, in which the data is incorrectly written to the magnetic medium, or hard errors, in which the disk itself has an actual physical defect in the designated area. CHKDSK fixes soft errors by overwriting bad data and resolves hard errors by marking that section of the disk as damaged and “restricted” for future use.
How To Fix
Since CHKDSK has been updated and updated repeatedly with each new generation of storage technology, the program continues to work correctly to analyze and repair any type of hard drive. The same process previously used to analyze a 160K floppy drive can now be used to analyze a 15 terabyte SSD.
Although there are many different ways you can use CHKDSK on a Windows 10 machine, the most common and common place to run this program is through Windows PowerShell, which is designed to replace the Windows Command Prompt.
However, because CHKDSK interacts directly with the hardware disk, it requires a special level of operating system permission known as administrative privileges. This simply means that CHKDSK is allowed to run as if it were the account that manages the computer.

The basic CHKDSK invocation, simply “chkdsk [disk]”, will scan the disk and display status information, but will not fix any errors.
So, in order to run CHKDSK in a mode where it can actually fix the problems it encounters, you need to add some parameters. In a Windows PowerShell program, parameters are additional commands that are appended to the end of the program name by preceding each parameter with a “/” character. In this case, in order for CHKDSK to perform a full scan and repair pass, we type “
The “/r” option performs the same tasks as “/f”, reporting disk errors and also tells CHKDSK to look for bad sectors and restore any readable information it finds there. The “/x” option tells CHKDSK to unmount the disk (free it from the operating system) before starting the process.
Scanning And Repairing Drive
The boot disk is the partition on your hard drive that your computer starts with. Boot partitions are special in many ways, and one way is that they require special handling for CHKDSK.
CHKDSK must lock any boot drive it scans, meaning it cannot scan the system boot drive when the computer is in use. If your target drive is an external or non-bootable internal drive, the CHKDSK process will start when we enter the above command.
However, if the target disk is a boot disk, the system will ask if you want to run the command before the next boot. Type “yes” (or “y”), restart the computer, and the command will run until the operating system is loaded, allowing it to gain full access to the disk.

The CHKDSK command can take a long time to run, especially when running on large drives. However, once it’s done, it presents a summary of the results, including total disk space, byte allocation, and most importantly, errors found and fixed.
The CHKDSK command is available in all versions of Windows, so users running Windows 7, 8 or XP can also follow the above steps to start a hard drive scan.
Cautionary note: If you run CHKDSK on an older hard drive, you may find that the hard drive space is significantly reduced after running the command. This result is caused by the failure of the hard disk, because one of the important functions performed by CHKDSK is to identify and block bad sectors on the disk.

A few bad sectors on an old drive are usually unnoticeable to the user, but if the drive is failing or has serious problems, you may have many bad sectors that, mapped and blocked by CHKDSK, appear to “steal” significantly. parts of your hard drive capacity.
If you don’t want to use the command line, there are other ways to run CHKDSK on your system. Perhaps the easiest is directly through Windows Explorer.
Yes, you can use the chkdsk command on an external drive. You only need to show that the command disk is executed.

Sometimes a disk scan with chkdsk may result in a message saying that the disk is still in use. If this happens to you, you should unmount the drive or boot the flash drive with Windows Recovery Tools.
CHKDSK is a very powerful tool for scanning and repairing hard drives on Windows 10 computers. By following the steps listed above, you can use this useful feature to optimize your computer’s performance and fix disk problems.

How To Recover External Hard Disk Using Cmd In Windows 10, 11
CHKDSK, a cmd command, is used to check for logical and physical errors in the file system (in computing, a file system is a way to store and organize files) and file system metadata on a Windows volume.
When used with options such as /F or /R, the CHKDSK utility can also correct logical disk errors and restore the integrity of a volume’s file system. But it cannot fix physical disk errors.
Note: Chkdsk for Mac is called fsck. Fsck is used in Terminal on Mac. But mostly, users use Disk Utility first aid to repair drives.

CHKDSK has various options that help users resolve various disk errors. and the /F and /R options are most commonly used. Both CHKDSK commands are used to fix logical errors on a disk. But in fact they are different.
CHKDSK / R: Check and fix disk errors. Also, find the bad sectors of the disk and try to recover read data from the affected sectors of the disk.
It should be noted that both of them cannot repair damaged files such as videos and photos on the target drive.

Most of you are probably confused by the same question “should I run CHKDSK /R or /F?”. As mentioned above, CHKDSK / R includes the functionality of CHKDSK / F and also has an additional analysis of physical disk errors.
CHDSK /R looks better, doesn’t it? not completely. CHKDSK/R takes longer to run than CHKDSK/F. This is because CHKDSK/R not only checks and fixes logical disk errors, but also diagnoses physical disk errors. Typically, the CHKDSK process takes about an hour for a 1TB drive.
So which one to use is up to you
