Gullydwarf Posted February 28, 2010 Report Share Posted February 28, 2010 Recently I tried downloading a almost dead torrent. I got really far (93.5%).I searched for another torrent containing the missing pieces and downloaded it. Compared with the files that should've been in the other torrent, size and type and stuff all seemed the same.So I deleted all the broken files from the torrent that was not finishing and put the new files (with exactly the same names) in the folder where they should be. Now forcing a recheck muTorrent keeps saying that it has 93.5% instead of the expected 100%.If it was a problem with the files themselves muTorrent should say they were gone altogether and start downloading new versions of them right? But it doesn't, it says exactly the same pieces missing as before I changed the files. Link to comment Share on other sites More sharing options...
DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 What pieces are missing? Link to comment Share on other sites More sharing options...
Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 I don't think that is really important.It's the last 12 files. some are missing beginning and end of the files and one file is completely missing. Link to comment Share on other sites More sharing options...
DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 End-pieces of files that are missing are pieces that are shared between files that you have and files you don't.Non-bug. Link to comment Share on other sites More sharing options...
Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 So how do you explain the completely missing file which is also not recognized on recheck?and can you explain more on how those pieces are shared between files and why?

DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 If the completely missing file has so much as ONE extra byte injected in the first piece, the whole file is considered corrupt.Pieces overlap files in multi-file torrents because of how multi-file torrents are mapped.Pieces are hashed as if they were on continuous file, not separate files.

Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 so how do you see if a file is corrupt?and if the files I changed were checked but marked as corrupted why then are the other 11 files still marked as downloaded (for all but some of the start/last pieces) and not as completely missing?Look dude, I know you like to give short answers but here your story just doesn't seem to make any sense, so you might want to think a little bit longer about it and tell me the complete story.

DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 My story doesn't make sense because you don't understand the bittorrent protocol at that level of the process.http://bittorrent.org/beps/bep_0003.htmlhttp://wiki.theory.org/BitTorrentSpecification#Metainfo_File_Structurehttp://forum.utorrent.com/viewtopic.php?pid=262290#p262290At that level of the process, the protocol has no concept of files.The file is DETECTED as corrupt because the .torrent file contains SHA1 hashes of the segments of the files in it. When a segment's SHA1 hash doesn't match the torrent, that segment is discarded as corrupt. Link to comment Share on other sites More sharing options...
Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 So muTorrent (at forced recheck) wouldn't say hey there's some files here that are corrupt?instead it just does as if nothing has changed at the files in question?That really doesn't make sense, does it?

DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 It would silently discard the pieces and schedule them for re-download.Just like every other bittorrent client out there. Link to comment Share on other sites More sharing options...
Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 but it doesn't do that on my torrent so what is the non-bug we are talking about here? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted February 28, 2010 Report Share Posted February 28, 2010 It doesn't do what?Unless your files match 100% piece for piece, they won't show up as complete, and uTorrent will attempt to re-download the missing pieces when started after a re-check.

Gullydwarf Posted February 28, 2010 Author Report Share Posted February 28, 2010 It doesn't do anything with it...It doesn't try to redownload anything and it doesn't show up as complete.I completely removed 12 files and put 12 other files in exchange for them. If there was anything wrong with the new files I believe it should have shown up on a recheck that all 12 files were removed and are being downloaded again. instead only the already missing pieces from the old files show up as missing.Why don't you even try understanding what someone is telling you before starting your "ow another one of those silly n00bs with a non-bug" routine.

DreadWingKnight Posted March 30, 2010 Report Share Posted March 30, 2010 Then your issue is consistent with the automated re-tagging done by some media indexers including the one included in windows media player. Link to comment Share on other sites More sharing options...
Gullydwarf Posted March 30, 2010 Author Report Share Posted March 30, 2010 ok, well the good thing is the files are all still readable, but I just would've liked to revive this torrent for 100% as there is still people trying to download it. But hey they can do with this I guess. Link to comment Share on other sites More sharing options...
Switeck Posted March 30, 2010 Report Share Posted March 30, 2010 You need to find out what's corrupting the files too...or you'll see that again in the future! Link to comment Share on other sites More sharing options...
Gullydwarf Posted March 31, 2010 Author Report Share Posted March 31, 2010 Well I would only play the files on WinAmp and cannot remember having them ever accidently opening in WMP. Maybe that was already corrupted before I got the torrent, because those missing parts are the reason why I replaced the whole bunch by files from another torrent.

moogly Posted March 31, 2010 Report Share Posted March 31, 2010 You can post Hijackthis log.Guide: http://forum.utorrent.com/viewtopic.php?id=29748Winamp has a media library and maybe it can retag your audio files. Link to comment Share on other sites More sharing options...
Gullydwarf Posted March 31, 2010 Author Report Share Posted March 31, 2010 I don't use the WinAmp Media Library I can keep track of my own files Link to comment Share on other sites More sharing options...
