Not enough blocks to repair

Hi all,

I'm having a nightmare trying to download.
I constantly have 'x blocks missing' errors when trying to repair.
I forgot to mention that I tried Quickpar and it had issues too.
Is there any way to download additional par files from somewhere?

I'm using Win7 x64, virgin media 20Mb.
I use giganews and newzbin mainly though I tried downloading an NZB from nzbs.org and same issue.
I have tried numerous times and numerous different NZBs from different sources and same issue.
Other files download fine.

I remember reading about a way to get more detailed logs from sabnzbd.
If you can tell me how to check these I'll take a look.

Thanks in advance,

Renaming files on Windows should not be necessary.
So if this is the cause, then there is indeed a problem.

If the problem happens on Unix, there's little we can do.
The cause is usually a careless uploader, using Windows.

I see this on every board.  There are many posts on Giganews that are not repairable if only Giganews is used to download them.
The fault is not with Giganews, the uploader, the newsreader or its user.  The posts are not repairable because Giganews was forced to remove pieces of them by DMCA notice.  If a fill server is added, no repair is needed, simple as that.  Saying that it's the uploader's fault or that there's nothing you can do is just wrong.

Hi,

Sorry for posting about the specific NZB I was downloading.
I emailed the NZB to bugs since it was only that specific item I was trying to download.
I then copy+pasted into here and forgot to remove the reference.

So, to recap, its most likely that the DMCA notice to giganews regarding specific items is to blame here.
Is there an easy way around this?
I seem to remember something about manually searching for missing items in RAW newsfeed or something?

Or, if I use an alternative newshost, do you think I'll be fine?
Any suggestions?

Thanks guys. :)

A DMCA notice will make Giganews remove the post from their servers.
So the only way out is to use another Usenet provider.
No search engine will solve this, as Giganews simply doesn't have the data any longer.

It depends on the DMCA notice.  Some notices contain all of the message-ID's for the entire post.  Other notices only contain message-ID's for the first article of each file, and a fill server easily solves the problem.  Due to the forum rules, I can't tell which is the case here.

A solution still requires an extra Usenet server.

Well, the downloads take a good long time and then fail in the repair stage by around 4-6 blocks.
So that sounds like it may be just a few msg-IDs that are missing?
So, if I was to use a free trial from another provider, I could use that as a fill server and finish the downloads?

Is a fill server only used for items that are missing from your primary server(s)?

Do you think its worth ditching giganews for another provider that hasn't been hit by DMCA notices?
Or are they all being hit by them?

Thanks guys. :)

I'm still just guessing that your issue is DMCA as I haven't seen a detailed log.

Highwinds providers (such as Newshosting and Usenet-news.net) are getting DMCA notices.

Buy a cheap block of bytes from Blocknews.net or Astraweb, which are not currently hit by DMCA but that might change.

Configure the cheap block account server as a fill server.  It must be set up this way when you start.

Don't use all 50 connections to Giganews, use less, probably a lot less.

The fill server will only fill in a few articles that are missing on Giganews, and the non-expiring block will last a long time.

I see no reason to cancel Giganews.

I set my downloads up last night almost exactly as you described there.
My only issue is that I used usenet-news as my fill server and as you mention, they may have had the same DMCA notice.
It would explain why I had the same issues anyway.
Again, still a few blocks short of a repair.

Where would I find the detailed logs so I can post them here?

TIA :)

I have accounts with Giganews and Usenet-News.net

So if you can trust a third party with having details of what you download, send me a PM that has some way I can find the post.

After one week of the forum rules preventing me from identifying the issue, I got a PM with more info.

The problem is DMCA and both Giganews and Usenet-news.net got the same notices.

Try one of the other providers I mentioned that did not get DMCA notices.

Thanks again for the help. :)
Got another block account now and set it up in SAB.
Is there any way to set an order of preference for fill servers in SAB?

Also, how can I check DMCA notices in future, should I see this issue again?

Cheers,
:)

I don't have the latest SABnzbd+.

The older version I have has a Connections tab where warnings are shown.  It's useful for troubleshooting without examining a logfile.  You never said anything about warnings shown on the Connections tab, if any.

The DMCA notices caused the first article to be removed from each file.  The warnings on the Connections tab include this information:

"partnum=1"

"missing from all servers, discarding"

If all the missing parts are the first parts, then it's DMCA (although some notices remove more than the first parts).
