Fix Corrupted Hard Drive Using CMD with a Detailed Guide

This MiniTool guide provides step-by-step instructions to repair a corrupted hard drive using the Command Prompt (CMD) and recover data before attempting repairs. A corrupted hard drive can lead to system crashes and data loss, but these methods can help.

Data Recovery:

If your computer boots normally, back up your files to another device using professional backup software (like MiniTool ShadowMaker). A free trial is often available. If your computer won't boot, use data recovery software such as MiniTool Power Data Recovery. This software can recover files from unbootable, formatted, or damaged drives. You'll need to create a bootable media using the software's bootable builder to access your files.

Hard Drive Repair using CMD:

Method 1: CHKDSK Command

The CHKDSK utility checks and repairs file system errors.

1. If your computer boots: Press Win R, type cmd, and press Shift Ctrl Enter to run Command Prompt as administrator.
2. If your computer doesn't boot: Access Command Prompt via Windows Recovery Environment (Troubleshoot > Advanced options > Command Prompt).
3. Type CHKDSK x: /f (replace 'x' with the drive letter) and press Enter. /f finds and fixes errors. Add /r to recover data from bad sectors.

Method 2: SFC and DISM Commands

These commands repair corrupted system files.

1. Open Command Prompt as administrator (see Method 1, step 1).
2. Type sfc /scannow and press Enter.
3. After completion, type DISM /Online /Cleanup-Image /Restorehealth and press Enter.

Method 3: DiskPart Command (Caution: This will erase all data on the drive!)

This method formats the drive, erasing all data. Only use this as a last resort after backing up your data.

1. Open Command Prompt as administrator.
2. Type the following commands, pressing Enter after each:
   • diskpart
   • list disk
   • select disk 1 (Select the correct disk number carefully!)
   • clean
   • create partition primary
   • format fs=NTFS quick
   • exit

Conclusion:

This guide outlines several methods to repair a corrupted hard drive. Remember to prioritize data recovery before attempting any repair that might erase data. Regular backups are crucial to prevent future data loss. Use caution when using the DiskPart command, as it will permanently delete all data on the selected drive.
