    Moving the tab on the disk itself is what makes it write protected.

    Besides, without telling us your OS/Compiler, there can be no anwer even assuming that there is one.

    Have you for example even read the data sheets for that device to find out if it's even possible?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
