Partition manager in Windows for volume and partition manipulation DISKPART

Credits to :


Windows does have a Disk Management tool for simple disk management operations. For USB drive or logical drive, if the drive already has more than one partition, Disk Management will not allow you manage extra partitions on removable storage devices, unless you deleted all of the partitions and make a new, full size partition. Disk Management will not provide delete volume option for extra partitions on USB drives if more than one partition is detected.


How to combine two partitions or more into one and restore USB drive to it’s original state?

To delete partitions on USB drive, you will need to use the command-line utility: Diskpart. Diskpart enhances the Disk Management graphical user interface (GUI).


When you use DiskPart to clean USB drive partition, all data on the USB will be erased.

Step 1, start a command prompt as an administrator (CMD)

  1. Click Start.
  2. In the Start Search box, type cmd, and then press CTRL+SHIFT+ENTER or right click choose “Run as administrator”
  3. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

Step 2, run DISKPART.

At the command prompt, type:


Step 3, List all disk in DISKPART.

At the DISKPART prompt, type:

list disk

Step 4, select your USB disk which you want to delete the partition.

Replace the * with your disk number from step 3.

At the DISKPART prompt, type:

select disk*

This command will delete the partition that you select from step 7.
