Bah! Use the read-toc command of cdrdao to extract the toc of the cd. HTH, Jens
From: Java Jive on 18 May 2010 09:31 Isn't that exactly what you want? That's certainly why I suggested it. I thought that the whole point was that you need to copy byte by byte from one device to another? Your current procedure is grabbing the audio data and making a mess of it. What you want is something - I'm not saying that it necessarily has to be DD, that was all that I could recall, but something - that does a pukka, faithful, sector by sector copy from one CD to another, without trying to 'interpret' the data as audio or anything else. BTW, you are using a destination CD of exactly the same size as the original aren't you? Not trying to copy from 740MB to 800MB or vice versa?

I've tried a few things from the man page for cdrdao, like removing the START field's value, removing the START field completely, fiddling with various values, but all I get is either a disk with forced gaps, or error messages. Its almost as if I've got the wrong the man page. -- *=( http://www.thedailymash.co.uk/ *=( For all your UK news needs.

T'ain't /me/ making the mess you mentioned BTW. :( -- *=( http://www.thedailymash.co.uk/ *=( For all your UK news needs.

Track 2 which is 4 1/2 copies of one short file has not silence after it. Track 3 which is the second half of the repeat of copy, and a few more There is no break on the cd between track 2 and 3. They flow into each otehr. Now your particular cd player may insert a 2 sec silence between the tracks but that is a problem with your player not with cdrdao.
