Diskpart's clean all versus Full Format
As I understand it (I was reading this thread Need HDDErase That will work with SATA ...), clean all writes all sectors to 0 on a disk. As I understand from post #13 by Brink, full format will set aside bad sectors so the disk uses only the good sectors when written. Does clean all have the same effect of cleaning up bad sectors, or is it purely for security by writing zeros?
