I beg to differ. Write protection is usually a hardwired protection on the disk drive. The OS and programs can, however, neglect to pay attention to this fact and try anyways. As an example, early versions of Twister (a skewed track formatter) have been known to "format" write-protected disks. That is, they went through the motions but the information on the disk remained intact.
