You can use Teracopy to copy folders / files with verification after copy. It produces checksums of the source and destination files that can optionally get saved to disk. You can also use Teracopy to validate these saved checksums. Another (freeware) utility that you can use to produce / verify checksums on individual folders / files is Md5Checker.

Here is possible that your download was corrupted. Download Md5Checker from http://getmd5checker.com/. Check iso file with it. Md5 checksum should be: c64cdf16381323980ec6a3f37b8b8087.
