To do this you need a special ROM on your DAT drive, SGI DATs are the only ones to have such a beast AFAIK. There is no known way around this problem - ever put a audio DAT tape into a DAT streamer ? my DAT doesnt like them and throws them out. > > I know he'd be *very* interested if there was, as he's been trying > > to figure it out for a few months (on and off). > > There's a lot more involved than just copying.
