dd copies only first 9.3mb of ~40mb CD
 

Greetings!

I have a data CD made as 2 sessions (an incremental backup of my server), and, like the first time I wrote to the CD, I used dd to make an image, then md5sum to make a digest.

After burning the second session, however, dd is only reading the first session -- 9.3mb. There should be nearly 40mb of data between the 2 sessions.

Does anyone know a way to make dd read both sessions to the same image file?

Could you please post the exact commands you used? In the meantime there is this thread, which you might search for hints:
