Hi I'm using Ktorrent 2.2.2, Kubuntu 7.04 and KDE 3.5.7 and the problem is that Ktorrent suddenly stopped downloading on my NTFS and FAT32 partitions. Now when I set the download folder in one of them it just says "Allocating Disk Space" and stays at that phase indefinetely.

A week ago I was using only NTFS partitions for my Win HDD but when that problem started happening I decided something gotr buggy with the ntfs-3g driver and converted one of the partitions to FAT. But the problem still persists...

I'm not exactly sure since when this started because for some time my NTFS partitions were full and i didn't download anything on them. I suspect though that the problem started since I downloaded Ktorrent 2.2.2 about 2 weeks ago, not 100% sure of course.

Any ideas why this is happening?


btw - another bug i noticed is that on my NTFS partitions fully downloaded files Ktorrent would start finding chunks of corrupted data in them and redownloading them. And what's very annoying - after sometime it happens over and over, again with the same files, even though there is nothing wrong with them, I've tested them and the HDD too - no problems.
What's interesting about them are that they're all torrents i downloaded recently, older torrents on these partitions do not get that bug.


Please help, even if it's for the first bug only.

You say you've tested the files and the drive. What drive diagnostics have you done? Sounds to me like a Hardware issue.

Well i checked it under WinXp, the normal scandisk, also PartitionMagic's disc scan and another utility - TuneUp Utilities 2007 which had a disc checker of its own, though it looked tome it did the same test as the windows scandisk, just with fancier graphics.

There were some minor errors but i checked on ntfs-3g's site and it was explained there that exactly those are not errors but only windows considers them so. Anyways they are fixed now and none of the diagnostics give me any errors, the problem is still here though, even with a different file system.

can you reccomend me some diagnostics under linux?

Sorry, stupid question, but did you check if you can write on the NTFS-partition from Linux?

Problems with the FAT32-partition might be, because of the 2 GB-issue.

No problem writing on the HDD, not with the NTFS, nor with the FAT32.

And the problem isn't because of the size either, because so far all the files in the torrents were maximum the size of a CD (700 mb).

What if you disable diskspace preallocation ? Does it then download properly ?

That works! Thank you very much!!!

I know this is an old thread, but it seems the issue is still relevant in my machine using version 3.3.4.

Does anyone have any suggestions for how to get pre-allocation to work on an NTFS drive when experiencing the issue where pre-allocation hangs?

Are you sure it hangs ? It's not that it is just taking long ?

I didn't fully verify whether it would eventually complete pre-allocation and I didn't go into any debug info. So, yes, it could be that it's taking a very long time. I'm pretty patient, so I did give it a couple of hours to complete before turning off pre-allocation and restarting the program. It was attempting to allocate ~30 gigs in one go. I suppose I could test it with smaller files to see if there's a difference.
