[plug] Comparing to CD's

[Dennis Plester]

I would have thought that your suggestion or a shorter variant of it would
work.

What burning package do you use? If it happens to be Xcdroast, and the disk
is only data, you can use the verify burnt image option. Once you have first
copied the original CD as a image on your hd and then burnt it, you can
verify the image on the hd with the one on the new CD. You could also if
required do the same with your friend's CD compared to your hd image.

This is probably not the best way, but if I'm using Xcdroast, which I do
most of the time, it's reassuring. (It doesn't work with audio, or mixed
mode type CDs.)

One of the things I've come to find with Linux CD burning is that it is much
more reliable than Windows, but harder to set up, and more difficult to know
whether a duplication has been successful. (Thankfully, my first observation
means that you virtually never need to worry about my third.) I appreciate
that this comment may inflame some members out there, but I am purely
relating my personal experiences.

Hope this helps

Dennis.

	Hi all,
		I have a quick question for everyone.  I have a friends CD.
I have made a
	copy and the duplication reported no errors.  What I need to do is
verify that
	the copy really was successful.   I still have the original CD.

	I thought something like:
	Insert Original CD:
	md5sum </dev/cdrom >disks.md5
	Insert copied CD:
	md5sum </dev/cdrom >>disks.md5

	then make sure both md5's are the same.

	Does that seem reasonable .... or is there a better way.

	Yours Tony.
