Regarding computer repair commands that start with 'r', the most common ones are those related to disk inspection and repair, such as the 'chkdsk' command where some parameters may involve 'r'. However` The chkdsk command itself does not start with 'r', but its commonly used '/r' parameter is used for more detailed disk checks, including scanning and repairing bad sectors.
The following is detailed information related to the 'chkdsk' command:
Basic command usage:` Chkdsk is a command-line tool used to check disks (usually hard drives) and fix logical file system errors. In the Windows system, you can run it through the Command Prompt (CMD).
/R parameter: When using the 'chkdsk' command, adding the '/r' parameter will perform a more detailed disk check, including scanning bad sectors of the disk and attempting to recover readable information (if possible). This operation may take a long time and is best performed when the disk is not busy.
Example usage: If you want to check and try to fix errors on the C drive, you can use the command ` chkdsk C:/ f /r /x`。 Among them`/ The 'f' parameter is used to fix errors on the disk`/ The 'r' parameter is used to search for bad sectors and attempt to recover information`/ The x parameter ensures that the disk is offline during chkdsk runtime to prevent other processes from accessing the disk.
In addition to the 'chkdsk' command, although computer repair commands starting directly with 'r' are not common, there are other important repair commands worth noting, such as:
sfc /scannow： Used for scanning and repairing system files. This command checks the integrity of system files and replaces damaged files with cached copies.
DISM /Online /Cleanup-Image /Restorehealth： Used to repair damages in Windows images. This command will attempt to fix issues with Windows images from Windows Update or the local Windows image library.
These commands are powerful repair tools in the Windows system that can help users solve various system problems. When using these commands, please ensure that you have administrator privileges and carefully follow the prompts. If you encounter any problems, it is recommended to consult relevant official documents or seek professional help.
