At least on reasonable OSes. E.g., did you try \\.\M: ? If Windows does not support this, one can just make an ISO image from the disk, and use FC (or diff). Hope this helps, Ilya P.S. In my experience, byte-per-byte comparison is not relevant. At least, I never saw a disk which could be read byte-per-byte, but the result would differ from what it is supposed to be. Disks with some unreadable sectors - a plenty (a hundred?); but if fully readable, then correct.

My apology to all since my original message is too vague. Here is what happening. My PC runs Windows XP, and I have ISO Recorder Power Toy installed ( from http://isorecorder.alexfeinman.com/isorecorder.htm ) It is a very nifty stuff. It uses XP's own utilities to burn ISO images (ISO files) to CD/DVD. All I need to do, if I ever want to burn a CD or DVD is to right click on the ISO image file. The first item on the right-click menu is "Copy Image to CD" and when I choose that, and choose the CD/DVD burner, the utility will automatically burn the CD / DVD for me. Which means, the is no "verify" (or file compare). In NERO or ImgBurn and many other CD burning programs they have the "verify" step to make sure that the CD/DVD burned is the same as the ISO image. And what I am looking for is a stand alone utility to do just that --- Read in an ISO-Image file, and then compare it to the (CD/DVD) disc that is on a CD/DVD drive, directory by directory, file by file, byte by byte. Again, please accept my sincerest apology for the vagueness of my original message !

I basically understood what you want/ed to do and I do not know of any such utility. You were given /so many links/, especially by "johnw" and you seem not to have bothered to check any of the links out. I wrote you a post earlier today before this latest "clarification" but did not bother posting it since all I said had already been said. While it is nice of you to "clarify" for the great unwashed, it would have been nice of you to THANK all the people (not just ONE) who gave you so much info. It doesn't happen with a snap of the fingers, you know - YOU were too lazy to just Google for the answer to begin with, weren't you? No one here is God, you know. We can't tell you of something that does not exist, while Google knows everything. Still, if you get a utility like WinImage (there are several), you can open any ISO file and write it to your HD and then compare the contents with what went into the ISO file in the FIRST place. I am not aware of ANY utility which can magically overcome the fact that AFAIK every ISO file burned from the same material by different programs will be slightly different, have a completely different checksum, and can not be "compared" bit by bit except to a copy of itself with a good file manager or a file compare program. Of course, the easiest, and free, solution would be to use imgburn - or to plonk down 40 bucks and get CDRWin from goldenhawk (which is what I have been using for years, started before imgburn - which is /supposed/ to be even better - came out) but if you don't want to do that and insist on using a plug-in instead of a real program, that's your problem. Just out of curiosity, does this miraculous plug-in allow you to set the burning speed? Or do you just burn everything at MAX like so many other modern "computer users"? No offense, it's just a little tiresome to see SO many good replies and then get a re-post which implies you haven't looked at ANY of the links and appear to refuse to accept any of the info given. BTW, ANY program the author of which proudly says "It is recommended by MSDN download site along with Easy CD and Nero and is used by a number of companies around the world." is (IMHO) to be avoided like the plague. SOME recommendation... MS made BOB, WinME and Vista, remember? But they STILL won't let you print the contents of a directory in ANY version of Windows without using the command line or a 3rd party program... The ONLY thing they know how to do is spy on their customers and make lots and lots of money... AFA Roxio and Nero, they make incomprehensible illogical pig bloat. Adaptec may have been the first - I remember burning a Quantegy/Ampex CDR with Adaptec software at 1x on an external HP burner which cost more than a good computer costs today, and Roxio is "related" to it, but I know of *few* programs that did not change for the worse (if not simply became complete trash) when the kinds of changes that Adaptec made in its company structure were made. (Let alone when someone just buys someone else out, a favorite MS/Adobe tactic of destroying quality competition.) AFA Nero, I find it simply insane. Anyone who uses either it or Roxio is not anyone I would trust to recommend a ball-point pen, let alone ANY software. -- The Onion: Is there a God? Winona Ryder: Is there a God?

I believe you need DVDSig. Small, fast, easy. . . :) Program: DVDSig Author: Dariusz Stanislawek Windows "all" Ware: (Freeware) http://members.ozemail.com.au/~nulifetv/freezip/freeware/ "DVDsig v1.01 [10kB]" "DVDsig is a files verification software for DVD-ROM, DVD-Video, CD-ROM and other removable media. It will scan all files and directories of a new disk compilation and create a list of reliable MD5 file signatures. DVDsig is small enough to be conveniently included on any disk compilation and offers immediate, independent verification of the files after burning is completed. The inclusion of DVDsig along with the signature list it generates is a simple, quick and effective way of validating your data at any time and anywhere."
