How to use chkdsk in windows 10 for Repair Error Disk? In the previous discussion, gave a tutorial on Hard Drive Repair and Check With Fast and Easiest regularly using cmd and Windows Explore.

Well, on this occasion we will provide a tutorial that is almost the same but different, namely on how to use chkdsk on the Windows 10 operating system to detect and repair and also rebuild an error boot sector or bad sector.

On your computer or laptop there is a data storage media known as an internal hard disk. Where there are millions of bits of data. Anything can happen to your computer. It is not uncommon for data to be lost or an error occurs, the battery runs out, the power goes out, the operating system is damaged, the application is corrupted, the virus, the trojan. These various circumstances can cause errors on your computer's hard disk. therefore you need to perform regular hard disk maintenance, one of which is chkdsk in windows.

What are the causes of hard disk errors?

Some of the things that are often the cause of errors on storage disks include:

  • The file is corrupted as it is being written. It can be an index file that refers to a corrupted file.
  • Deleted files, files that have been damaged or corrupted by other programs, viruses, trojans or other malware.
  • Physical damage to the hard disk.

You need to know that a hard disk drive (hdd) is more at risk of physical damage when the disk spins and data is physically written on it (filled with data), the more data, the more potential for physical damage to occur.

Hard disks with the Solid State Drive (SSD) type already use a memory chip that is used to record data such as RAM, so this SSD tends to be unstable, which means the data will be retained even when your computer is dead.

Tutorial how to Use CHKDSK in Windows 10

Before demonstrating the tutorial above, a little knowledge about CHKDSK. This is a tool provided by the Windows operating system which essentially functions to perform a low-level scan on the hard disk or other similar storage media to search for, find and repair any errors, errors or damage to the hard disk both external and internal.

So, this CHKDSK utility can detect physical and data damage and fix errors that occur on the hard disk. When there is damage to the hdd, through CHKDSK it can mark the parts of the disk that are physically damaged so that the Windows system knows not to use the damaged part or error. This happens when the hard disk is damaged and really can't be repaired.

Below is a tutorial on how to use the chkdsk command in Windows 10. Read the complete step by step below:

  • In the Windows search box, type the keyword “cmd” without the quotes.

  • To check your hard disk for errors and fix them at the same time, type the command “CHKDSK D: /f /r” and then press Enter.

The process of scanning and repairing disk errors will depend on the capacity of the disk partition being checked and also depending on the specifications of the computer. The larger the capacity of the hard disk drive, usb flash disk, external hdd, the longer the scan time will be. Likewise, the higher the specifications of the computer and the RAM on the computer, the faster the HDD scanning process will be.

If you run the CHKDSK command on drive C or the drive that contains the operating system that is being used, then the command will run after the computer restarts or reboots and this CHKDSK will run before Windows or the computer starts.
