MediaCloQ CD protection bypassed

fadden used our newssubmit to tell us that he has bypassed the new MediaCloQ protection with CDRWIN.

With this burning software by Goldenhawk it was a piece of cake to extract the tracks.


A computer running Win98SE with a Plextor 40max CD-ROM drive saw the disc as having two sessions and 16 data tracks. My CD player only saw 15 audio tracks. This feature alone makes the disc difficult to rip or copy, because the software doesn't see any audio tracks, and a CD-R copy would be full of tracks that even a CD player would see as data. Another machine, with a Plextor 12/20 and a slightly different set of software, seemed to have a lot of trouble figuring out what the disc was. It eventually sorted things out, but I get the sense the disc has been tweaked in ways that confuse the drive firmware.

I tried using "Session Selector" to select the first session and then access the tracks. This resulted in a Plextor 8/20 CD recorder becoming unusable until a reboot. I'd guess the firmware got confused.

The next thing I tried was to crank up CDRWIN v3.7a (section (6-1-7)), and extract some tracks using my Plextor 12/20. No dice -- the display showed 15 unselectable tracks and 1 MODE-2 data track.

Next, I tried the "Extract Disc/Tracks/Sectors" function, selected "Extract Sectors", chose "Audio-CDDA (2352)" for the data type, and entered a nice range (0 to 300000, where each audio sector is 1/75th of a second). This choked when trying to read starting at block 173394, so I tried again stopping at 173390. This resulted in a rather large WAV file, which I opened with Cool Edit -- revealing the entire contents of the disc, plain and clear. Playback revealed no audible defects


There are probably other ways to bypass this protection, but if you are in need, here you got one of them. Let us know your experiences !

One item mentioned on the site but not in the above article: this experiment was done with the Charley Pride _A Tribute to Jim Reeves_ disc that is available at retailers (e.g. amazon.com). If you'd like to verify the results, get the disc and download a demo version of CDRWIN.
