        Yes , After formatting it on an RLL based controller .
        Also 'some' of the RLL controllers would recognise a st506

        To the best of my knowledge there never was an Segate labeled
        st-506 that was RLL encoded .

        Yeah I can understand that one . Did you use the rll controller
        to transfer the data ? or ?

        YES !!! , Of course I was quite happily suprised at the speed
