How to clean and repair drive with DiskPart on Windows 11

To use DiskPart to repair a drive on Windows 11, open “Command Prompt” (admin), run the “DiskPart” tool, select and clean the drive, create an active primary partition, format the storage, and assign a drive letter.

On Windows 11, you can use the Check Disk (chkdsk) tool to scan and repair logical errors on a drive, but if the Task Manager continues to show one hundred percent active time on a drive, you’re still unable to access it, or you notice other problems, it could be a data corruption problem which you can resolve with DiskPart.

DiskPart is a command-line tool for managing drives on your computer. Usually, you would use the tool to set up a storage device, but if you’re having problems, you can use it to clean and repair the drive. Of course, this assumes you are dealing with a logical problem, not a hardware issue.

In this guide, I will teach you the steps to use DiskPart to revive a secondary hard drive on Windows 11.

Important: The instructions outlined below will delete any data on the drive. It’s assumed you have previously created a backup of the data you may need again.

These instructions are suited for repairing secondary drives, such as a second drive you may have installed to store data, or external drives and even flash drives. If the drive with the problem is the drive where the operating system is installed, then you can use the Check Disk tool or the DISM and SFC tools. In the case that the installation continues with issues, Windows 11 includes a feature to reinstall the operating system, keeping your files, settings, and apps.
