Need help recovering a game disk

[BladeofSorrow]

Hello, first off I would like to apologize for breaking forum rules yesterday by asking for an original game file. I do own the original and would gladly post cd pics to back up that claim if needed.
Now to my problem, I have a defective 3rd disk for Warhammer Mark of Chaos. I have tried copying the files to hard drive on 3 seperate systems and always get a cyclic redundancy check error.
I downloaded a file recovery program recommended on this forum but I couldn't get it to find my dvd drive either.
Cleaning the dvd did nothing.
Changing the language settings also was not the problem.
I have contacted tech support repeatedly months ago and have since given up.
Can someone please reccomend a way to recover the data on the disk so I can play the game again? Thanks
