Thanks! That explains it well! Helpful to get a couple second opinions that 
the "error" can be safely ignored.

Also good to learn the block size for CD's, since I'd been assuming it was 
1024. Just for grins I tried the bs=2048 control with a dd rip, but it still 
reports "Reached End of Media" error.

appreciated
peace
