I had problems with bin1 and 2 (dl'ed off Sprocket US), along with (of course) a non-matching hash. I was away for a few hours today so I decided to try downloading again, but I only got a different, still non-matching hash.
For my third try, I decided to use the torrent, as that would guarantee me uncorrupted data, even if I get better speeds from the http download. However, I then realized that, as long as I set the torrent location to the same place as the corrupt file, it would scan it and only retrieve the damaged parts. 5 minutes later I had a matching hash, a lot less time taken than another 4gb download.
If your download's hashes don't match, try using the torrent to fix it.
