Is there a way to verify a CD image (.iso) after it has been burned (and either the CD burning software does not have a "verify" option, or it was not used at the time of burning)?

I tried ripping the CD using dd and comparing the md5sum of that image and the original, but they don't match. I didn't really expect them to, but I'm pretty sure this disc burned without errors (I just want to be sure since this is a master disc to be sent off to be duplicated).

ImgBurn has the ability to do this.

  • Verify - Check a disc is 100% readable. Optionally, you can also have ImgBurn compare it against a given image file to ensure the actual data is correct

Perfect! Thanks – Brian May 11 '10 at 15:03

Nero can do that. It has a checkmark (turned on by default) when you burning a CD.

I know that many CD burning programs have an option to verify immediately after burning, but I want to compare a disc that has already been burned with the source image. – Brian May 11 '10 at 14:31
