HI ZUKI,
I have the 9000 too. I will be happy to try to help you with questions, problems, needs, etc., as others on this forum have done for me. I have had it for only a few months so I am still learning but willing to share.
I would suggest Vince Cochrane for the hard drive. I am super pleased with the unit I got from him, ready to drop in, formated and loaded with songs and styles. He is in UK. His service was second to none. I am pleased and will deal with him again I am sure.
Much happiness with your new board
