SABnzbd Forums

I find myself in the exact same situation.... I found this tutorial on quickpar

http://www.binaries4all.com/quickpar/

It seems to me I would run Quickpar, and Quickpar would tell me which files are damaged, is that correct?

but then I'm not sure... how do you go about re-downloading the par2 files... is it listed on the original post?

I was also wondering, if I just deleted a few of the files at random, would sabnzbd try to download those again, and at the same time, maybe try to download anything else it seems to be missing?

Thanks...

No, you'll have to get by with par2.

If your job is still in the history as a retry job
it's probably easier to delete the most damaged files.
The smaller the file, the more damage. Except for the highest .r?? number.
Then just click retry and SABnzbd will re-download the missing files.
If there is an NZB with more par2 files, you can add that to the retry.

well according to your explanation, which I understand, a file smaller than lets say 50MB would indicate damage.  The smaller the more damage.  

There is 164 rar files in that job.  Most (if not all) except the very first RAR file are less than 50MB, with sizes like

48.8MB
49.4MB
46.3MB
47.5MB......

Are they all damaged?  If you are right then I'd have to delete them all!!!  Is that right?

EDIT: I ran

par2 r -v *par2 in the job folder and par2 confirmed most of the rar files to be damaged.....

OK I've experimented a bit with par2 and so far same problem accross the board:

Not enough repair blocks.  par2 says:

Repair is not possible.
You need X more recovery blocks to be able to repair.

How do I get these extra blocks?

This SABnzbd is amazing...

I deleted a group of the smaller rars, changed my server (astraweb) and reran the job.. it downloaded the missing parts and all was good

on another job I just deleted the smallest group, retried but it still wasn't good enough, then deleted the next smallest group and retried and it worked great...

excellent!

From a search engine like binsearch.info. Look for the common part in the file names.
That's your only hope if all files miss a little bit.
Otherwise you will have to re-download
