zEEwEE probably noticed the fuss about audio copy protections and found himself having a protected audio CD. He started to do a little research and reported his experiences on his own webpage.
He already submitted this story a few days ago, but in this article he suposes that the CD is protected with the new MediaCloq protection. I think he is wrong and that this CD is protected with the new Cactus Datashield protection:
I recently wanted to make a personal backup of my own CD called "The Loveparade Compilation 2001". CD2 copied fine, but CD1 could not be read by any CD-ROM player or CD burner. It would however play in any normal audio CD player. Now as a decent reverser you must understand my frustration 😉 A friend tried copying this CD with a custom audio CD copier (Philips CDR 765) which actually worked. But if you haven't patched yours to be able to write low-cost non-copyrighted CD-R's with it this is quite expensive. This copy will be able to be grabbed on a normal way. |
So, next evenings I spend trying to understand what was going on here. I found out that after insertion the laser first goes to the center of the CD (the TOC or Table Of Contents where the index of the CD is stored). After this the laser went to somewhere on the outer side of the disc and started to try to read there. This is where the reader would never stop doing this and some players will hang forever in this phase.....
So what idea could be easier than to prevent the reader from reading this outer part? I made 3 paper stickers of about 25 x 20 mm and placed them on the outer side of the CD. Now the reader would read the inner TOC, then go to the outside again and after not being able to read anything there because of the stickers, the reader would be 'smart' enough to decide to stick with the inner TOC, go back to the center and read this TOC as the one and only TOC 🙂
Well zEEwEE's method might be a little to tricky for most of the CD Freaks visitors, there should be an easier way. I would love to know if using this method is violating the DMCA.
