I've encountered drives like that before, where the polarization notch was backwards. Sometimes it was intentional, other times the plastic shroud was accidentally installed backwards.
Usually the solution was just to hunt down an unpolarized cable. It is also fairly easy to sand the polarization bit off of a polarized cable. Usually there is no easy way to modify the drive itself.
Of course, check the technical documentation and make 100% sure the drive is designed to plug in to an IBM PC style floppy controller. Usually they are, but some very weird drives did exist.
