No. The Terms might be confusing, but this is how Sony called it in their library they linked into Hi-MD Music Transfer Software for the Mac. The idea of "erase" is that the traces of any Hi-MD structure are completely erased, and the idea of "format" is that the medium contains data in the right format to store Hi-MD tracks. To add confusion, the operation executed by the "Format" command (C2/01) is named "Erase All" in the Walkman menu, and the operation executed by the "Erase" command (C2/00) is called "Format" in the walkman menu and also only available on classic media. > I have committed the changes to the code according to your > information.

The complete blanking is only useful if you want to reuse a MD medium in a non-Hi-MD device. Maybe offer it as extra option. > Btw, what do you guys think on implementing playback control in > QHiMDTransfer once we got sending SCSI commands working? Shouldn't be much of a problem. But this is not what sfbp requested in the channel recently. He talks about reading the tracks via USB, decoding them (regardless of what DRM says) and sending them to the sound card in real time. This means the Hi-MD DRM needs to be cracked for that. Regards, Michael Karcher
