[gentoo-user] Verification of audio CD copy?

[Mark Knecht <markknecht@gmail.com>]

Hi,
   I've got a bit of a problem recently with (I think) k3b. Over the
last couple of months *some* copies of CDs made in k3b using the Clone
Copy feature do not reliably play in my car's CD player. I've tried
multiple CD spindles and I've tried burning the copies on two
different Gentoo machines - one 32-bit and the other 64-bit - with the
same results. The thing that is VERY strange about this problem is
that some CDs and all copies of those CDs play fine. For other CDs the
originals play fine but every copy I make fails, and if they fail,
they fail using either Gentoo machine to copy them. (Hope that's
clear....)

   I'm wondering if there is a program that can verify the contents of
each CD against each other, bit for bit, to identify whether this is a
problem on all of my computers or whether it's something about my
car's CD. The strange thing is that the original CDs play fine in the
car. It's only the copies that sometimes don't, and it's only the
copies of *some* CDs, not all CDs.

   I've been using these same machine and same car CD player for years
and everything has always been fine. Now for the last 2-3 months
nearly 50% of what I copy fails.

   Anyway, thanks in advance.

Cheers,
Mark
