Ok so bear with me.
An Audio CD has different ‘tracks’, right? Not the songs, but like an audio track, a data track etc. Only the data track contains a proper filesystem (and normal block sizes) as we know it, but all tracks contain sequential digital data that could technically be represented by a bitstream. Correct?
So when I put a CD in my drive, CLEARLY the audio track is accessible (because I can listen to it, rip it with cdparanoia etc.). So obviously my computer is able to access all data on this CD, even in the non-data track.
But when I go to the raw device file, /dev/sr0, that file represents merely the data track stream, or so I’m told. So I can’t just dd it and have a full copy that contains all information?
Then where the hell does cdparanoia get its information from if it’s not exposed as the device file? And how do I create a full copy of a disc, completely agnostic to what it contains, file formats, file systems etc – just bit for bit so I can work on it later?
