Computer CD drives are supposed to do more error detection because silently reading corrupted data is worse than refusing to read the data. However, if a drive behaves just as "dumb" as an audio CD drive, it can read "protected" CDs without problems. It is _not_ possible to prevent anyone from reading audio CDs because audio CD drives still must be able to read the data digitally from the CD. > It does affect several hifi-CD-players as well though, for example > mine. Many modern CD players use a computer CD drive because there isn't much of a price difference between those and audio CD drives anymore. > > On Wed, 31 Mar 2004 10:03:30 +0200, michael heubeck wrote > > > which progs can i use? only commercial-ones? Many protection schemes rely on wrong data in a second session on the CD. It would be possible to create a CD image, insert appropriate errors, and then burn it, but there are no free tools for this AFAIK. Clemens
