File degradation

by Guest on 2019/11/21 07:01:04 AM    
Hi,

Not sure if this is a Tixati issue, OS, physical or FS issue but I am hoping someone can point me in the right direction.  I have Tixati setup to download to HDD1 and once the torrent is complete I transfer it to any number of other HDDs that I have.  Most torrents transfer just fine but every now and then I notice if I recheck the torrent that it will go from 100% so some lesser amount.  I am running Tixati on a Debian Linux based system with the drives formatted with ext4.  Any suggestions or ways to trouble shoot this?

I should mention that the underlying files are not deleted by me and this also happens with singular files.

Does the overview really show files missing and redownloading a piece? I bet I've had these situations with other clients that it's just a sort of visual bug.

I guess the easiest way to see if it's all right: remove download from Tixati but keep files. Download the file again onto another drive. Then check if both downloads match, e.g. with md5sum.
If it's really a problem with the drives, it maybe won't even show up on first try. Though have you checked SMART stats of your HDDs? I recommend GSmartControl for a GUI tool.

It's not a visual bug that is for sure.  I ran into this problem when I used another client (as some trackers don't allow Tixati) to cross seed a file that had already completed in Tixati.  For example. downloaded a 30GB~ remux and when I checked it with the other client it only reported 25% had been downloaded.  Rechecked with Tixati and sure enough Tixati also reports only 25%.  Looking at the distribution of the pieces there is no pattern of missing data.

Drive looks okay to me but I have to admit I am no expert in reading this output.
