CHKDSK(The full name is Microsoft Check Disk, which means disk check) is a command program that can run on DOS , OS/2 and Windows operating systems . When the system has a false crash or an illegal shutdown, the system will call it to check the disk , and the user can also manually call it to check a certain disk partition through the command line . The program generates a disk status report based on the file system used by the detected disk , and if parameters are provided , the program can also repair logical errors in various disk file systems.

Commands and parameters
When running CHKDSK, if you do not specify /f or any implicit /f parameters, CHKDSK will only display the disk status of the detected disk, and will not make any changes to the disk. If /f is specified or the parameter of /f is implied, the corresponding operation will be performed on the specified disk according to the parameters.

parameter list
| volume | Specify a drive letter, mount point, or volume name. |
| [path]filename | Specifies the path and name of a file or set of files to be examined by CHKDSK . Wildcards (* or ?) can be used to specify. |
