Question dd if=/dev/sr0 I/O error


I want to make an .iso file of a disc with audio on it. I can do it through K3B for example but any other program has a real problem with doing anything with disk. dd gives me error like that:
Code:
dd: czytanie „/dev/sr0”: Błąd wejścia/wyjścia
0+0 przeczytanych recordów
0+0 zapisanych recordów
skopiowane 0 bajtów (0 B), 0,00769673 s, 0,0 kB/s
md5sum is no better than dd:

Code:
md5sum /dev/sr0
md5sum: /dev/sr0: Błąd wejścia/wyjścia
If i change sr0 to cdrom or something it changes nothin.

dmesg gives me a strage output:

Code:

I wonder if this CD was copy-protected somehow or what? How to obey this and also I would like to know if it's possible to copy copy-protected disks with a dd command and how? Is there any "how to" on the Internet? I couldn't find it really. I don't want any misunderstandings. I don't want to copy disks for illegal puposes I simply do a backup copies with almost every disk. I know it's sometimes against the license but I think that I'm doing no harm to anyone by this.

In fact k3B didn't create a raw disc image. It just made *.wav files on hdd from audio on a CD.

An audio CD doesn't have a filesystem.
