I downloaded all of the ISO files for Fedora 3, and then proceeded to burn them to a cd. The first 2 images burned fine and the md5 was correct. However, when I tried to burn discs 3 and 4, I got an error in nero that was something like "cannot read data". I then tried to check the md5 sum on the files using fsum, and it said that access to the file was denied. I then double checked to make sure that the file sizes were correct, and they are. What could be wrong? I`ve tried a few different mirrors with the same results. Why are these files corrupt?? Any help would be appreciated.
