The media on a HD diskette is much much more dense than that on a 720K diskette. It is my understanding that at the factory(s) the diskettes are tested for density and those that pass are marked HD and those that don't are marked DD. I wouldn't trust MY data to such a diskette. One of the faculty members that I support, who used DD density diskettes formatted HD for backing up data, had data on one of the diskettes just sorta fade away, he has since invested in HD diskettes and transferred his surviving data.
