readcd -> nur Fehlermeldungen
Hallo,
ich hab mal in
/usr/share/doc/cdrecord/README.clone und
/usr/share/doc/cdrecord/README.copy
gestöbert, und bin auf "readcd" gestossen. Kannte ich bis Dato nicht.

| The best way to copy a data disk is to copy the raw data on the master CD.
| This may be done by reading the data from the raw device by using 'readcd'.
|
|
| NOTE: All CD-R's written in Track At Once mode end in two unreadable
| run-out sectors. If the disk has been written with a Yamaha CD-R100
| or with a Yamaha CD-R102, there are even more run-out sectors.
|
| For this reason, you will not be able to read such a CD correctly with 'dd'.

Ich hab also eine Datenreiche CD hervorgekramt, und wollte das mal
versuchen, dieses 'readcd'.
Es wirft nur Fehler! (sind unten angehängt¹).
Ich hab alle möglichen Gechwindigkeiten ausprobiert, bishin zu speed=0
(readcd dev=1,0,0 -speed=0 -clone -f=rawdisc)
Zur Hardware:

Über die readcd-Version kann ich gerade nix sagen, ich weiss gar nicht
aus welchem Paket das kommt - wie ermittel ich das?
Was ist das Problem von readcd? Die CD ist ein Originalmedium,
schlecht lesbar kann es also nicht sein - lässt sich ja sonst auch
ganz normal lesen.
