You download Fedora cora 8 more than once, through Alturrent

When you use the -c option with sha1sum, the file should be a file that contains the hashes to be compared, not the ISO itself. Download the text file SHA1SUM from where you got the ISO and put it in the same directory with the ISO. Then run the command like this:sha1sum -c SHA1SUMI know that looks weird, but that's how to use the -c option. For more, read the HOWTO (http://www.fedoraforum.org/forum/showthread.php?t=166240).

It looks okay now. You have a good Fedora ISO, and the rescue CD ISO was not in the directory. The -c option makes sha1sum try to check every file listed in the SHA1SUM file which contains hashes for two files.
