Cactus Data Shield Tries Again 378
autocracy writes: "Midbar, an Israeli company that developed the breakage of standard called Cactus says that they have released more than 10 million CDs to the U.S. and Europe. They now claim that there will be no issues playing it but you will lose quality if you try to copy. I'm just wondering how it is that you can play it on a system at perfect quality, but when you copy it things don't sound right. Do they not know about optical output? Lame quotes including comments by the makers of how this is a 'proven technology' can be found at C|NET."

It merely needs to copy track 1 explicitely, all 2774 bytes per block on a Plextor or at least 2352 in raw mode.
Macs and PCs will soon have updated THIRD PARTY cd drivers that will play any of these things. One system will suffer the most... the newest macs... thats because to eliminate EMI audio noise, the macs force users to use digital audio extraction over ATA-ATAPI bus and SCSI bus exclusively. This is fine if the media is not heavily damaged in some sections, but these corrupted disks slow down firware in standard audio extraction modes used on macs. Apple got rid of all their A-D converters, even for audio mics. And now that thier audio D-A out is in usb and uses usb speakers no mother board interference and disk drive head interference emits on speakers cranked to 500 watts.
I miss track-0 tricks, its cool to see the world using it 10 years later.
It explains why some cactus cds can be copied except the first audio track, with older tools.
as for CDDA logo rights being removed by Philips.... Philips abused the tradmark symbol themselves!!! They placed it on some european audio CDs in 1994 that were 79 minutes long. That was in explicite violation of the CDDA logo standard that maintains a maximum of 333,000 blocks of audio allowed (74 minutes)
Even since that day, Anyone is morally allowed to violate the CD-DA standard logo because it MEANS NOTHING now and is abused even by Philips.
I wish there was a manufacturer symbol I could trust to look for that meant REALLY-CDDA not violating *ANY* part of the "Red Book" whatsoever. Then these Cactus abominations from hell could be avoided.
Sony and Universal will soon shut down web sites that explain how a cheap 5 cent resister tied across the leads of a decrypted-USB speaker input can be used as audio in source into a D-A audio card to extract formaerly-protected encrypted limited-access audio.
ha!
long live the resister!

This makes *big* assumptions about how the cd supplies data in audio versus data modes, and is apparently not true for all cdroms (and very few dvd roms), so does not always work.
it also assumes that an audio cd player uses a 'standard' interpolation method, any that use a different (maybe even improved) method will produce less accurate 'solutions' to their intentionally introduced errors.
hmm, the whole thing is a house of cards, and will no doubt fall over before long.

How would this be unplayable?
CDS works by purposely introducing errors into the audio data on the disc. Audio CD players are supposed to interpolate across the errors such that there is supposed to be no difference in sound quality. But CD-ROMs--being designed to read data CDs where every bit has to be correct--don't do this interpolation, and thus they see the disc as having lots of errors and crap out. You can't make an exact copy of the disc if your CD-R can't read it.
At least that's what's supposed to happen. It has since come out that 1) many DVD-ROMs read the discs just fine; and 2) *certain* combinations of CD-Rs and ripping software can manage alright.

But, what happens if someone in CA happens to visit KY and sees your CD in a store in KY? If they liked your music, they may just very well buy your CD. That would *never* happen if it wasn't distributed far and wide.
I firmly believe that artists should be paid for their work and I do agree with you in principle that it is wrong for people to enjoy the fruits of your labor for free. But I also do know that as a result of mp3s and file sharing, my purchases of CDs has jumped by a factor of 3.
So I don't wholly subscribe to the argument that filesharing and mp3s is complete theft from artists or is detrimental to the future of the music industry.

I thought I'd buy the Fast and Furious 2 to see if the copy protection really works. The "cd" of course said I could return it if defective. I went to return it and it was a no go. I tried to explain that it didnt work, but they didnt get it.
BTW eac is able to fix the defective TOC and then rip. Not sure about the ripped audio quality, i'm not an audiophile.

Don't bother waiting to contact your representatives until the record industry makes its move; it's already done it, and their position is quite clear: they do not intend for us to have unlimited duplication rights or probably even limited duplication rights for -any- reason, including Fair Use, in the next generation of music media (DVD-Audio and the rest), and they would clearly enjoy stamping out duplication rights in the current generation (CDs). If this disturbs you, contact your representatives now with a simple explanation of the situation, your problem with it, and a copy of Boucher's letter to the RIAA.
Take a look at CDDA Paranoia website (Score:5, Informative)
One of the answers on Paranoia FAQ [xiph.org] nicely explains all of the problems with ripping CDs, and generally all of the differences between playing CD on audio CD player, and reading audio CD as a stream of bits with a computer. These differences are exactly what is addressed by all of those so called "copy-protection" techniques.
The "copy-protected" "CDs" have to be played by audio CD players (otherwise no one would buy them), but not ripped with computers (like it made any problem with copying them, even if it's possible to make CDs completely unplayable on CD-ROM drives... When will they learn?) so all they can do, is to address the differences [xiph.org] between them. It's very good to know, how it really works.
The legend of characters on Paranoia progress meter [xiph.org] gives a good introduction to what Paranoia can and what it can't fix (yet):

The latest version of ExactAudio copy [exactaudiocopy.de] ripped White Lilies Island perfectly using a Toshiba DVD-ROM drive, after enabling C2 error correction.
I don't know if this is the drive or the new version of the software making this possible, but it is definitely one of the CDS protected CDs since it won't rip with anything else (and has the CDS logo on the back cover).

My experience with a copy-protected CD (Score:2, Informative)
So, I brought the CD over to a friend's room, asked him to try it in his machine, and it worked just fine. In both his drives. Go figure.
Of course, the worst-case scenario is that I had to use analog ripping, and pump the output from a CD player into the line-in on my soundcard. It'd take all of 5 minutes to wire up, and would have to be done in real-time... To the best of my knowledge, there is no way to protect against this kind of copying. And if push comes to shove, I'm sure that mp3s will appear on the net which have been ripped via this method.

The truth is out there (Score:2, Informative)
In addition, their "protection" degrades the actual audio quality over time, because they're essentially using up the error correction bits for data. You need error correction to do just that - correct errors. You waste them on something else, like correcting purposefully-inserted errors, and you end up with a disc that is much less robust and able to withstand wear and tear.
This means that you must rip and burn a new copy of any Cactus disc you buy as soon as you open the case for the first time. And you must rip with multi-pass validation to help ensure that you got the correct data off the disc.
Any claims by Midbar that their protection is just peachy are BS.

Which means that you'll have to click the little "Install Anyway" button when you install the drivers? So what? It still works.
Secure Audio Path applications can tell whether or not a device's driver is signed and will not open a device with an unsigned driver. If a media player insists on the Secure Audio Path, it will not output through Total Recorder.
