Thanks again Alex - I've tried RW's and setting different speeds - no difference. I've tried everything I can think of since last June when I first reported it. It always comes back with that message and, y'know, sometimes, when you get a feeling in the seat of your pants that this is the way it's always gonna be....., well, that the seat pant feeling here. In some ways I feel that I should go buy another drive, but I repeat, it works OK with everything else, as a couple of other people have also reported.....
Best wishes - Jim
