OSXI I had heard some amazing things about Drive Genius, but hearing about a $5 charge to download an update is troubling. In professional music software there is copy protected software that requires registration for it to work, and to get updates. There must be many ways that the developer could "verify" that the people downloading are registered customers. Also, to here about people loosing their whole drive while defragging is not very encouraging. I hope these issues get fixed and policies changed, because I've heard other good things about this product.
