My objective is to make a working copy of a Blaupunkt TravelPilot E CD, that ist TAGES-protected.
Therefore is studied M.Spath's article "Another Tages blunder" http://www.myce.com/article/Another-Tages-blunder-212/ to get in contact with this matter and the used tools. Thank you Michael for this excellent tutorial!
The way to do Spath describes in his article is more or less clear for me.
1.) Make an image of the copy protected CD using CloneCD --> getting 3 files: *.ccd, *.img, *.sub
2.) Dump twin-sectors from the copy protected CD using Spath's tool "twindump".
3.) Insert the twin sectors using Spath's tool "twinsert"
4.) Cut the image using Spath's tool "imgcut"
5.) Analyze the image to see, if the sector layout is consistent between img and sub.
The details are described in the file "ttools.txt": http://upload.cdfreaks.com/tools/ttools.zip
So far, so good ...
Now my question to point 2: How can I determine, in which sector-range of the CD the twin-sectors are? According to the size of a CD there can be a lot of sectors:
74 Minutes - CD = 333.000 Sectors
80 Minutes - CD = 360.000 Sectors
90 Minutes - CD = 405.000 Sectors
99 Minutes - CD = 445.500 Sectors
When I use Spath's tool "imganalyze" I get the excat number of sectors of the CD's-image.
One possibility to get the sector-range of the twin-sectors is to use Spath's tool "twindump". I can set the range from 0 to the number of sectors of the CD's-image, determined by "imganalyze". But when I do this, the little tiny proggy works for hours and hours and there is no end. If you select a small range, the proggy works fine.
Another try was to use Jackass's tool "TwinRange", that is also provided in the archive ttools.zip. But this doesn't work.
So, how can I determine the sector-range of the twin-sectors of my copy protected CD?
Thank you for your help.
