True, they called it HiMD. The drives could also up-format the older MD disks to get a bit more storage.<p>That said, i think there was a version of the original MD format sold as a data drive in Japan. I think Sony had a model or two of their Vaio laptops with it built in.<p>That said, what basically sunk the format was slow write speed and that the Sony Music tail was basically wagging the Sony Electronics dog. The MD was from day one laden with DRM, and the HiMD took it even further (want to put those MP3s on there? Had to format convert to Atrac via some crazy program. And the only way to get them back out was via the analog hole).<p>This just at the time as large capacity flash was coming to market, and you could dump any random MP3 onto them with a drag and drop operation.
