How to Use Windows Disk Management

Following are the ways you can use this tool. Let’s start, shall we?

How to format a partition with Disk Management in Windows 10

You can Erase/format an already created partition in your PC, but you should know that formatting a partition/drive will erase all the data in that drive. So if you are formatting a partition just because you are facing some issues like bad sectors, viruses in the partition you must take a backup of your data in an external disk drive.

Here’s how you can do it:

  • Open Disk Management
  • Right-Click on the drive, you want to Erase/Format.
  • Click on Format, and wait for the format to finish.

Format a partition

Change the Volume Label if you want to as per your choice and click on OK to start the Format process. As you can see in the below screenshot, you can checkmark “Perform a quick format” for faster formating. I will not recommend this option if you are formatting the partition to troubleshoot an issue.

Similarly, you can also “Enable file and folder compression” , doing this will save you a lot of space on that partition. The system will compress the files and folders to reserve space whenever a new file/folder is created within the partition.
