If you attempt to delete files from or reformat a hard drive, and you receive the notification that the disk is write-protected, you can execute a series of commands to remove the read-only attribute from the drive. Use the Diskpart command line utility to remove write protection from external and internal hard drives, as well as USB drives. The Diskpart utility is installed with all versions of the Windows operating system. However, if your computer is connected to an enterprise network, your account may not have the necessary permissions to run the utility. Consult with your system administrator for more information.
