The command-line interface known as Command Prompt or CMD is used to run shell commands. You must use each command at the command prompt precisely. You might be interested in learning what hard disk issues the Command prompt can fix. Given below are the features to repair a corrupted hard drive:
- Use CHKDSK to Repair Hard Drive
- Try Diskpart to Repair Corrupted Drive
- Run SFC Scan
1] Use CHKDSK to Repair Hard Drive
The check disk software enables users to scan for logical and physical disk defects by looking at the file system and file system metadata of a particular volume. Additionally, it is connected to several switches that can carry out various tasks. Let us see how to use CMD to repair a corrupt hard drive:
Step 1: Open Command Prompt as Administrator.
Step 2: Copy and paste the following command and press Enter to execute it:
chkdsk X: /F
Note: Change H with the letter of the hard drive you want to restore or repair.
There are a few other parameters you can add to the command line in addition to the /F one. Here are the various parameters and what they do:
- /f- Locates and corrects all hard drive errors.
- /r- Finds any corrupt sectors on the disk and restores readable data.
- /x- Unmounts the drive before the procedure begins.
- /b- Removes any bad clusters from a disk and rechecks all allocated and free clusters for errors. Use it with NTFS File System.
Step 3: To run a more thorough scan, you can modify the program to include each option. In that situation, the G drive's command line would be:
If you fix an internal drive, the application will prompt you to restart the computer. To restart directly from the command prompt, press Y and Enter.

format fs=ntfs quick
After formatting, the confirmation message DiskPart successfully formatted the volume will appear, after which you can close the elevated command prompt window.

Step 3: Type the command sfc /scannow and press Enter to run it.
The application will begin checking the integrity of all protected system files and replacing any damaged or missing files. Keep the Command Prompt open until the evaluation is 100% complete.
If the hard drive is external, run the following command:
sfc /scannow /offbootdir=X:\ /offwindir=C:\Windows
Note: Change x: to the letter the external hard drive was assigned. Remember to substitute the location where Windows was installed for C:\Windows as well.

- Manual damage: Improper human actions like an unexpected power outage, removal without safe removal, improper system shutdown, etc.
