I burned a 100 GB disc with video in CDBurnerXP. After the burn it verified the disc as failed. I'm not sure if there are some slights of error in some videos in them, because they can all be played.
I verified it again with ImgBurn and it didn't show any errors. I as well edited an image file to make it different from what it was as source. So now on my disc this file is different and on the disc it's the "original", yet verification didn't pick up that change, so makes me wonder if the verification doesn't spot errors as this and only looks for disc scratches, which is strange as CDBurnerXP gave me a fault, and it's probably correct because I was using my PC during the burn.
How can I make sure with any other verification that the files on the disc are 100% correct as the files on my disc?
