Disabling Hard Error Pop-ups

A number of times recently we’ve seen discussions about how to disable hard error popups in a kernel driver.  For example, a driver that wishes to probe the floppy drive does not want a dialog box to pop up as a result of its probe.  This is easily achieved using the function IoSetThreadHardErrorMode, which will  ensure that the annoying dialog box does not appear.


Correct usage for this is:


    BOOLEAN oldHardErrorMode;


    oldHardErrorMode = IoSetThreadHardErrorMode(TRUE);

    // perform protected operation

    (void) IoSetThreadHardErrorMode(oldHardErrorMode);
