Write protection on a DVD is used to keep its contents from being erased. If you have a DVD that you want to copy (or write) over, you won't be able to do so until the write protection has been disabled. The only way to disable write protection is to format the DVD; do this through the Windows 7 operating system.
Step 1
Open the optical drive on your computer and put the DVD into the DVD tray. Close the drive and allow the computer to bring the DVD onto the screen.
