Working with Windows 7 professional. While trying to format western digital 250GB sata laptop drive; receiving error not initialized. Went to elevated command line to diskpart to clean all; received error message write protected. Went to Disk Management & Virtual disk drive shows as disk 2 not initialized. No format options available greyed out. Went back to command line tried to see attributes disk is read only. How do I take owner ship to change the permissions & format.
