What is chkdsk.exe?

The chkdsk.exe is the main executable file for the Check Disk Utility. It is part of the Microsoft Windows Operating System, developed by the Microsoft Corporation. The executable is a system tool and command in Windows used for disk maintenance and repair.

Here are the functions of chkdsk.exe:

  • Chkdsk (Check Disk) checks the integrity of a hard disk and fixes various file system errors.
  •  It scans the file system and file system metadata on a disk volume to ensure their integrity.
  •  Chkdsk can repair errors on the disk, such as bad sectors, cross-linked files, and lost clusters.
  •  It can also recover readable information from corrupt disk areas and move data to safe locations.
  •  Chkdsk can verify the file system’s logical structure and repair inconsistencies.
  •  It provides a status report specific to each file system, showing errors found in the file system.

How do I run a chkdsk scan?

1. Using File Explorer

  1. Open File Explorer by holding Windows + E keys together.
  2. When it opens, right-click on the drive you want to check and select Properties on the context menu.
  3. Once the Properties window opens, click on the Tools tab. Under Error checking, click on Check.

2. Using Command Prompt

  1. Hold the Windows + S keys simultaneously, enter command in the search field.
  2. While holding CTRL and Shift keys down, press ENTER to start Command Prompt as an admin.
  3. When you receive a prompt, click Yes.
  4. When Command Prompt opens, enter chkdsk followed by the drive letter of the specific drive you want to scan and fix. For example, if you want to scan and fix errors on drive D, type chkdsk d:.
  5. Chkdsk can be run with different parameters, such as /f to fix errors automatically and /r to locate bad sectors and recover readable information.
  6. After entering the command, press Enter.

Can chkdsk recover corrupted files?

Yes, chkdsk can recover corrupted files to some extent. Here’s how it works:

  • When chkdsk detects file system errors or inconsistencies on a disk volume, it attempts to repair them.
  •  During the repair process, chkdsk may recover corrupted files by locating their fragments or moving them to safe locations on the disk.
  •  Chkdsk can recover readable information from areas of the disk that are still accessible, even damaged file system metadata.
  •  It can also fix issues like cross-linked files, where multiple files reference the same disk space, and lost clusters, where file data is stored in unallocated space.
  •  However, chkdsk’s ability to recover corrupted files depends on the severity and nature of the corruption.
  •  If the corruption is extensive or the file data has severe damage, chkdsk may not be able to recover the files fully.

It is important to note that while chkdsk can help recover some corrupted files, always have regular backups of your important data to ensure data recovery in case of severe corruption or other unforeseen issues.

In conclusion, chkdsk.exe is critical to maintaining your system hard drive. Chkdsk is only useful for local disks. The command cannot function with a local drive letter redirected over the network. An executable that functions similarly to this executable is autochk.exe.

To be able to run the command, you must be in the local Administrators group, or equivalent. Do not attempt to interrupt chkdsk while it is running. However, canceling or interrupting chkdsk should not corrupt the volume further than before running it.
