Just for future reference, Amazon sell IDE drives for the Tyros 2, and because all the files you are likely to save to it are very small (kb not mb) an 80 gig drive will allow probably 1000s of files to be saved and use very little space. I mentioned 80 gig as a good choice because the thickness of the drive needs to be taken into account when buying as the larger the drive capacity the thickness of the drive increases, if it becomes to large it will not fit in the Tyros 2 hard drive holder, the thickness has to be under 1cm - 80 gig fits nicely and you are unlikely to want more space!
