Hi All, I'm looking to write CDs and DVDs with (relatively) important data on them. I'm building a filetree, using 'mkisofs' to turn that into an ISO image and then using cdrecord to burn it onto the appropriate media. So far, so good. How can I verify that the media has recorded correctly ? Do I have to mount the media and check each file, or is there some way to verify the media itself against the ISO image file ? I looked at 'readcd' but it doesn't appear to do what I want - it actually seems to have some difficulty reading the CD. Any ideas ?
You could read back the data from the CD device using dd and then compare what you get back with the original ISO.
