is there a way to verify a disc thats already been burned, with it source disc image on the hdd?

i copied a disc as a disc image on my HDD, and burned the image, but forgot to verify it. i closed the program, but i wanted to know, is there a way i can verify it after the fact? via Nero, or Imgburn, or something else? im running Win. 7 64-bit. HP. thanks!

ImgBurn has an option "Verify Disc".

Specifically, "Verify Against Image File"?

edit - haven't tried this and not sure exactly how/how-much it compares, i.e. the data in each block (e.g. CRC flags).

edit2 - confirmed! scenario -

1 - write CD1 from ISO1 using Nero

2 - write CD2 from ISO1 using Nero

3 - create ISO2 from CD2 using DVDInfo

4 - Verify CD1 against ISO2 using ImgBurn (fairly fast)

It appears to work just fine (strictly sector-by-sector compare).

Or, take the long and slow path and compare the MD5 sum of each file on the ISO and the CD. For those with nerves of steel...
