Anatomy of Cactus Data Shield 182
meehawl writes: "This is a good analysis by CDRInfo on the current version of Midbar's Cactus Data Shield. This is the format Universal will use to protect its new audio CDs. It's been reported here already that some DVDs effectively bypass this protection, but this article addresses the specific concerns of how best to backup these protected CDs, and how to extract the music data at high quality for download to a personal MP3 listening device."

You're forgetting that most people will never have any problems with playing these CDs.
They use dedicated CD players not CD-ROMs.

They managed to copy the disc with CloneCD [elby.org] and the Aopen drive. They also tried to copy it whith one other drive (TDK CyClone 161040), but that one encountered read errors.
"The CDS200 cd-r backup does contain the CDS200 protection, however now is FULLY readable from all tested drives"
Translation: Rip away.
Also interesting to know is the amount of read errors in the original versus the copy. The diagram can be found here. [cdrinfo.com]
In short, the "real" cd was one solid block of read errors, the copy had a few spikes, but those were nothing compared to the other, both in frequency and seriousness (note that the scale in the two diagrams is vastly different).

Screw you, asshole.
I have a plethora of mp3 audio playback devices. My car, home and portable personal devices. These devices have been on the market for over 4 years now and sold with high visibility advertising, so you know for a fact they exist and people are using them. Yes, I rip everything to mp3 so I can listen to it MY WAY, on MY EQUIPMENT, in my home and elsewhere. I place the CD I bought in a locked cd storage cabinet and that's where it sits until it's needed again. Now let's look at something else, what about the phillips CD recorder, compiler. Many more people with these or their computers like to make compiliation cd's. for their own personal use.
I am sick of your type of self-ritious attitude that marks everyone with an mp3 playback device, a cd burner, and linux or other non MS operating system as the pirates of the Carrabiean or Evil thieves. the cd's I bought ar my property, I can listen to them how I want, and I will...
and my atitude is the attitude that needs to be taken by everyone that hears someone even try to imply what you said... get in their face.
