∟"readcd" - Read Raw Data From CD

This section describes a tutorial on how to read raw data from a CD-ROM by sector locations.

Another tool in the "cdrtools" package is called "readcd", which allows you to read raw data from any CD-ROM by given sector locations. "readcd" takes an option called "sectors=<start>-<end+1>".

Here is what I did to read the sector on CD where the README.TXT file is located.

C:\>\local\cdrtools\isoinfo dev=0,0,0 -l | find "README.TXT"
---------- 0 0 0     1733 Dec 11 2006 [32841 00] README.TXT;1

C:\>\local\cdrtools\readcd dev=0,0,0 sectors=32841-32842
