I'm pretty sure francois
is indeed referring to copying an audio disk/CD to an ISO file on the hdd.
You do know that a CDDA or commonly known as an Audio CD is not
an ISO disk?
I know that Nero (including the Linux variant that was available for a time) was indeed able to copy an Audio CD into an nrg file (Nero's own ISO-like file format), but they had to add extra headers or else it would not work.
An Audio-CD differs compared to an ISO data CD or a Video-DVD (which is also not an ISO image) that it not only stores the audio data digitally, but it also stores information by having the music data pressed more or less "deep" into the layer of the CD. And that's the reason why a written at high speed Audio-CD often fails when played with non-PC-based Audio CD players, cause the "deepness" of the Audio-Data is usually not considered when writing an Audio-CD at high speed. [Creating an image prior writing is helping in this regard quite a bit] I am not sure if I am able to get the info about the technical stuff right, because no native tongue and such.
But it is ages ago since I last did such stuff, for more info about such things go to https://forum.doom9.org/
. This was and probably still is the
best net resource when it comes to digital video, DVD or CDDA reading, writing and converting.
And no, I have not the time nor will to research all that CDDA magic again, if someone is interested do the research for yourself.
The rest I wrote below is why but since its not really necessary to know about since it just gives personal reasons, but no technical info or help about th thread's matter, I put it into a very small font.
I just had a operation on Monday (that was planned as ending part of the work trip I took, since I had to be at that place anyway, so i combined the work and the medical necessary treatment) and it will take some weeks till I am again at my usual level, so all I do is in RL and in my "online life" is being in energy savings mode, so to speak. Mentally and physically, since my body wants to use as many resources to heal the best and quickest it can, and I want to support my body in that the best I can by avoiding all unnecessary stress or unnecessary stuff of any kind, but that also means my usually favourite pastime, long hours in nature, is also not possible right now.
And no, currently not even laughter is the best medicine, since the the kind of operation that was, with the cutting open and such, gives me pain attacks at the stitched wound cause it is near the area you contract involuntarily when you laugh, or cough.
