Cannot delete Volume on USB

“I am in Computer Management. I am the owner of the USB volume, there is no sharing, the partition is empty, and I can't delete it since the Delete Volume option is greyed out. So why it happens and how can I delete it successfully? Any ideas, thanks a lot!”

Why Disk Management cannot delete volume on USB?

Deleting the volume on USB flash drive is usually considered as an effective way to free up disk space, clean the disk or fix some other disk errors. But sometimes it can be a tough task since the “Delete Volume” is unclickable in Disk Management. This issue always happens on previous versions of Windows OS, where your USB flash drive is regarded as a removable device. And the operating system does not allow users to delete partition on this kind of device. Besides, only 1 recognizable partition can be created on removable device.

If your system is Windows 10 Version 1803 or later versions, you can easily remove partition on USB drive since Windows 10 1803 already supports this operation.

How to delete volume from USB successfully in Windows 11/10 PC?

Does the above explanation imply that is there no way to delete partition on USB stick when Disk Management cannot do that? Absolutely NO! Apart from using Disk Management, you can make use of Diskpart or a professional disk manager to perform such operation.

Precaution: If there are some important files in this partition you will delete, please make a backup first via free AOMEI Backupper.

Method 1. Delete volume on USB using DiskPart

DiskPart is a command-line utility Windows 11/10 operating system offers. With the DiskPart, you can remove the write-protection from USB, create primary partition and more. So when the Disk Management cannot delete partition on USB drive, DiskPart is a nice alternative.

First of all, type cmd in “Search” box, right click CMD.exe and run it as administrator to enter CMD window, then input the following commands (each typing ends with hitting on “Enter”).

  • diskpart

  • list disk: all the hard drives on your computer will be displayed.

  • select disk n: n stands for the disk number of your USB (here we take disk 1 as example).

  • list partition: a list of all the partitions on the USB will appear.

  • select partition n: n is the number of the partition you want to delete (ex: partition 1)

  • delete partition

Delete Partition Diskpart

If you want to delete all the partitions on the disk, just retype selection partition number and delete partition. After deleting every partition, you can type “create partition primary” and hit enter to create a new partition on the USB drive.

WARNING: DiskPart is a command based program, so it is easy for computer users, especially the newbies, to make mistaken operation. If you type a wrong disk or partition number, you will delete the wrong partition and lose everything inside. In this case, you can use a professional partition recovery wizard to get it back.
