    Hi,
    please forgive me Im new to C# and have identified a defect with a program I wrote.
    the app reads a CD\DVD and generates an MD5 checksum of the contents, and this info can be used at a later stage to verify the disk.

    the defect I have discovered is during the verification, upon testing the first disk all is grand,
    however if I enter a second disk (same ISO burned on a different disk) the operation runs allot faster,
    and does not appear to actually read the media device, so I took the second disk and scratched it to the point where I cannot copy from it, and followed the above and it "reads" the data and passed.
    however if I load a different disk and run a verification of the scratched disk the process correctly fails.

    Any guidance would be appreciated
