Mixed Mode NRG Image Verification vs. Actual CD Copied From?

Hi.

I was just copying one of my old mixed mode CDs & the 1st program I tried to copy it with failed with an I/O error. I then tried to copy it with Nero & Nero completed successfully outputting an NRG. However since the 1st program had an I/O error I’m a little doubtful the Nero copy is 100%. While I can verify the data tracks with md5 sums I don’t know how to verify the audio tracks vs. the image Nero made. Does anyone have an suggestions on how to do this?
(Note: this is not a copy protected CD so the I/O error was probably due to the CD being old.)

Use CloneCD or blindrite.
