Torrent Error: Element not found.

[Nhoj]

I had been using the app on Vista and had never come across this error. I then installed on my XP machine and was getting it a few mins on every d/l - I tried the various settings as listed in this forum but nothing helped. I have now changed my defauly directories from a networked hdd (mapped as S:) to the C drive and fingers crossed every thing seems fine so far.

[klankymen]

I've got version 1.8.2 (build 14458), and I'm getting this error on one torrent now as well.

-operating system is windows 7 (though I've downloaded several dozen torrents in 7, this is the only one giving me problems)

-I'm downloading to a local NTFS drive, with a fairly short filepath (F:/uTorrent/Files/)

-my bt.compact_allocation is set to "false"

-my diskio.coalesce_writes is set to "false"

-my diskio.sparse_files is set to "true"

-my diskio.coalesce_write_size is set to "262144" (1/8 the original value)

-I've done force recheck

-I deleted the .torrent file and redownloaded it (but kept the downloaded files)

I followed all the suggestions in this thread, also I searched the FAQ, but no mention of "Element not found" in there.

I'm sorry if I'm doing something wrong in my search for help here, I'm new to the forum, and it seemed this thread would be the appropriate place to post it. Also if you need more information, please tell me what else I should give you / where I can find it.

I had not encountered this problem with my old set-up on a Maxtor 320GB Shared Storage II NAS and an older version of BT.

I now have the D-Link NAS DNS-321, 2 x 1TB drives as well as above poster, but mine is set up in RAID 1 array. I also upgraded to the latest BitTorrent build (6.1.2) and started downloading torrents from scratch. (Did I mention how badly the Maxtors suck? Yeah, my torrents are all gone.)

After reading this thread, I unchecked the "Disable Windows caching of disk writes" and re-checked the torrents that were coming up with the error. They all seem to be working now. The troubled torrents were all from various sources and so far it doesn't look like I've had to delete and reload the trackers. They are all downloading all their bits happily.

[Searinox]

This morning I wanted to download a torrent with 11k files and I kept getting this error every few minutes.

Here's something interesting. I had been using uT for 2 years and up until one particular torrent today I never had this issue. So when I found it out naturally I figured it must be the torrent. But having been given such a vague response(all I was told was that the torrent's main folder is causing the error, no file specified) I was forced to try other clients.

When I checked with Vuze, bingo. It reported a duplicate file. I set it to not download it and then came another, then another. I then went back to uT and meticulously started unchecking all the duplicate files in that subfolder. It downloaded successfully.

I know a torrent shouldn't have 2 or more same-name files in the same folder, but I find it kind of stupid that only Azureus knew how to report the correct issue, and how ALL clients ground to a halt and stopped downloading as soon as they tried to download the duplicates instead of continuing to download the others.

[Switeck]

WOW, very helpful to know!

...Was that torrent created by BitComet/BitLord/BitSpirit by any chance?

[Searinox]

I have no idea what it was created with. I just know it had over 50 files with the same name but different sizes and thus different hashes. I found it amazing how none of the clients even reported the problems when I added the torrent, especially since they were all set to pre-allocate. Instead they just tried to download as normal, then choked as soon as they hit the dupes' pieces.

[Switeck]

uTorrent can tell you -- under General tab, Created On: gives a date, time, and BY.

BitComet has a history of making buggy .torrent files.

[Searinox]

"11/06/2009 06:35:37" is all it says. No client name. I could in theory upload it here since all of it is public domain work and there's no copyright infringement. It is however, adult. If you have the resources to create a malformed .torrent yourself(I do not) then you should be able to reproduce the uT error. I think it needs a handle to report dupes, if any, when confirming to add the torrent, and list them before the user, informing them that they will not be downloaded.

[Switeck]

Please do not upload it here nor provide a link.

Just knowing that it's same-name files in the same folder is probably news enough.

[Searinox]

Ofcourse I won't. By the way I found out how it ended up that way: it's being uploaded off a Linux server. Makes sense why all same-name files had caps differences now. Many were jpg and JPG, or capped/uncapped first letter. I guess it must be a normal thing between Linux users(what file system were they using again?), but not Windows. But the Linux-server-going-down-grab-content-via-torrent-while-you-can scenarios are extremly rare. More often than not it's likely to be a faulty torrent file. Even so, it is news that Linux -> Windows torrents could routinely bump into this and not know what hit them.

[Firon]

It's not technically invalid, but it is a problem that Windows clients would have to deal with (by auto-renaming files, like we already do for a ton of other characters not allowed on NTFS).

[Jdrewrd]

dutch's solution of unchecking "Disable Windows caching of disk writes" completely solved my problem. I was having this problem any time a torrent was for some reason stopped and then restarted. It would not write to my DLink NAS. Im using Windows XP.

[Richard Choi]

Does anyone have an example torrent that has multiple files in the same path that are equivalent outside of case? I am having trouble generating and seeding one to test with uTorrent.

[fowl]

Like a file with trailing spaces or periods or something?

"Fred "

and

"Fred"

Would be equivalent on Windows right?

[Richard Choi]

My understanding is that the error will trigger if you have a multifile torrent with:

a.jpg

a.JPG

The problem is that you can't make and seed such a torrent or path in Windows or Mac easily... if anyone has a test torrent it will be easy for me to fix this issue.

[moogly]

@Richard Choi:

You can test with this .torrent made from a random picture found on Google.

Original picture: http://img3.imageshack.us/img3/4382/amphi1.jpg

Contents of the torrent: http://www.mediafire.com/file/yiklm2tozzt/amphi.torrent

\amphi\amphi1.JPG

\amphi\amphi1.jpg

A funny thing is when you are downloading this torrent without seeder (availability 0%):

if you move the picture .JPG or .jpg (downloaded from imageshack.us) into the empty folder \amphi created manually and you force a recheck, uT displays 100% of availability, as if one file instance present in the folder is enough to complete the torrent (likely because Windows is not case sensitive).

[Richard Choi]

Thanks a lot moogly!

[Switeck]

Network Attached Storage (NAS) drives might be able to have 2 filenames in the same location that differ only by case...if the underlying OS and format for the drives are Linux.

[fowl]

I don't think that SMB is case sensitive.

[Richard Choi]

Thanks, think I should have it fixed for a future revision.

[darkclaw]

I am getting this error after I updated to 2.0 BETA 17427, but I think it is because ESET is finding a virus on the torrent:

12/5/2009 12:49:05 PM Real-time file system protection file *** probably a variant of Win32/Genetik trojan cleaned by deleting - quarantined Event occurred on a file modified by the application: C:\Program Files (x86)\uTorrent\uTorrent.exe.

[Firon]

Probably a false positive.

[quasar3c273]

well, hello from the ending 2010...

i got this error on v2.2 (23703) on win7 ntfs. bt.compact_allocation is false.

re-checked the files and everything is ok so far. keeping an eye on it.

one of the possible reasons - i had small free space on that drive.

[myxomoP]

had the same problem, and i can say for certain that in my case it was only on account of having low disk space. usually utorrent reports insufficient disk space as its own error. why it chose this one instead i have no idea.

[quasar3c273]

myxomoP, i had this error later, when had enough space. the thing helped me: i stopped the torrent, removed .dat file, rechecked and started again.
