I´ve still got my good old GEM WK 6 here in my living-room. For quite a long time I haven´t been using it on stage any more (because of Audya and before that Korg); but nevertheless I still like playing it, and so it´s a pity that the internal hard disc doesn´t work any more - as that´s where my beloved Hammond sounds are (were?). So I might be interested in a way to solve this problem. Any suggestions how to do this? Thanks.
