What do you mean by CRC errors? Are warnings about articles that have CRC errors?tpas wrote: Did that... When the download has been succesfull (without crc failures) the commandline par2 and unrar work perfectly, when there were failures par2 sometimes is able to correct, sometimes not. The disk seems to work OK.
BTW: do you use a multi-code version of par2?
I'm not sure what you mean...
Or is is that unrar reports CRC errors?
The proper test would be to take an NZB, remove a few articles from it, let SABnzbd download it without post-processing.
Then run "par2 r" from the commandline and unrar too.
There's the classic par2 by Peter Clements and there's a mulit-code version by chuchusoft.
The latter sometimes gives trouble.
You can see when you just type "par2". When you see only Peter Clements name, it's classic one.
Other versions will have other names added, like chuchusoft.
BTW: unrar doesn't have a spotless reputation on Linux either.
The ones from the repositories are notoriously weak, especially the "free" ones.
Make sure you use a very recent one downloaded directly from the rarlabs site.
