Haha, well this is funny -- I'm back! I forgot all about this topic, but now I need to use this CD again and it still has the problem. What do you mean by "non bases ISO"? If it just checks the disc and compares it with nothing, what's the point? I checked the logs as recommended. Here they are. I've blanked a couple details, but everything should be clear. ; //****************************************\\ ; ImgBurn Version 2.4.0.0 - Log ; Friday, 04 July 2008, 13:37:04 ; \\****************************************// ; ; I 13:29:14 ImgBurn Version 2.4.0.0 started!

What does this command do exactly? With one burn, I verified it against the original ISO correctly, but then the non-ISO-based verification turned up some kind of confusing I/O error!

Hey folks, I have a question about burn verification using MD5 checksums. I want to be able to check my burns from time to time against the source images, to be sure no corruption has occurred due to disc scratches or whatnot. But I don't want to have to heft around 600+ megabyte ISO images on my PC just for verification. So here's the thing. After you've burned an ISO and when you try to verify the DVD against the source image, ImgBurn calculates the checksum of the ISO file the same way checksum programs like FastSum or MD5summer do. Then it somehow obtains the checksum of the DVD and compares them, and they (hopefully) match. However, checking the ISO file each time you want to verify the DVD is redundant, because it will be the same each time. I'd much rather have a bunch of stored MD5 files on my PC, each of which would already contain the checksum of one of my ISOs, and then I could just compare those MD5 files with the checksums of my DVDs. That would solve the storage problem I mentioned in the first paragraph. As such, I'm looking for a way to verify a DVD burned from an ISO against a saved MD5 file, instead of a saved ISO, which is the way ImgBurn normally uses. Does anyone know of a way to do this? Or essentially, does anyone know how to obtain the checksum of a burned DVD, one that should be the same as that of the original ISO? All the programs I've used just calculate the checksums of every file on the DVD, which isn't what I want. Or, is there some way to do this in ImgBurn itself? Any help would be appreciated.
