DiskPart is a useful utility when it comes to managing the disks on a computer. Even if the GUI based disk management tools on the Windows 10 operating system fail, DiskPart always tends to work. This does not mean that it cannot encounter any sorts of errors. If you see a message DiskPart has encountered an error, Access is denied, then we will show you what you need to do to fix the problem.
