SonicStage software occasionally causes irreperably damage audio files. This is a fact. I have lost several discs during title labeling, downloading and especially during recording. The "Cannot Record Cannot Read" error message means that the disc and all of the data is irreperably damaged. Sony has the recovery program but will not release it to the public. Moreover, Sony acknowledges that Hi-MD was not field tested. Sony does not take responsibility for selling the hi-MD--it is a lemon. My own experience with Hi-MD as been disappointing. I do not recommend this product. Don't make my mistake. Save your money and wait for quality to catch up with technology.Lee
