CD/DVD check tools
Actually cdck is a simple program to verify CD/DVD quality. The known fact is that even if all files on the disc are readable, some sectors having bad timing can easily turn into unreadable ones in the future.
To get an idea about disc cdck reads it sector by sector, keeping all reading timings and then tells you its verdict. Optionally it can write timing table into text file usable by gnuplot(1) program, so you can draw some graphs out of it.
