Files being damaged

I had a similar issue about a year or so ago where my tv show episodes were getting corrupted when sonarr moved them to their respective folders. I resolved that by eliminating the external USB drive I used to process the files and up to a week ago everything was fine until now.

I’ve noticed that for example The Blacklist S02E11 [WEBDL-1080p] at approx. 11:22 into the show is defective. However, when I re-downloaded it from the same source, it played just fine before and after the move. This has been happening with most of the TV show episodes I download.

Does anyone have a similar issue? It is so frustrating and I can’t figure out what to do.

Any advice would be greatly appreciated.

Thanks

i had this also a few time,
when i redownloaded them with sonarr incl move they worked.
so i don’t think it’s sonarr,
i use for usenet still NzbToMedia and it has a option to filecheck the video file for corruption.
so it shouldn’t happen anymore with usenet files.
