CRC error w/split zip in PA 11.50.61

dragon57

I just installed V11.50.61 and created a split zip file from one of my VMware image directories (about 32GB’s worth of files). The creation process went ok, but upon trying to unzip the file or perform a zip ‘test’ process using Winzip 11, I get a crc error part way in. Let me know what other info you may require.

TIA

spwolf

does it work with PA?

dragon57

Sorry, I should have been more clear. Not only do I get a crc error in Winzip when doing a ‘test’, I get a crc error with PA when trying to unzip it.

spwolf

ok, and how did you create the zip file, what options did you use and what interface did you use (shell or main PA).

thanks!

dragon57

I right-clicked from Explorer and selected “Compress with options…”. I then only changed ‘Multiple Disk Spanning’ to ‘DVD (4.7GB)’ leaving Method at Deflate and Compression at Normal.

When I test the zip file with Winzip, I get the following in a requester.

WinZip

Error in file #19: bad Zip file offset (Error local header signature not found): disk #3 offset: 365750754.

OK Help

When I try to unzip the file with PA, somewhere around the middle of the operation, I get an extremely wide requester with jumbled text displayed.

spwolf

i tried the same and it worked fine, so it might be a bit more specific that just large file.

Can you create an screenshot of error in PA please?

dragon57

Here is the pic.

spwolf

does it compressing that file without splitting work?

dragon57

Yes, compressing the directory contents without splitting works fine.

spwolf

ok, let me try to reproduce it with 50 GB test case and lets see what happens.

thanks

Here is the directory listing in case it helps duplicate the problem.

spwolf

can you try creating same archive, just via main PA window and see if that makes any difference please?

thanks!

dragon57

Just tried it. Same problem.

ivan

Also, please try creating same archive without spanning feature. So we can see if whole - big archive is OK for the beginning.

spwolf

@ivan:

he said it works, just spanning doesnt.

spwolf

@Activation:

same for me the zip does not work. it all makes PowerArchiver say unusable.

french version. (windows 7 64bits RC1 and WIndows vista 64bits SP2) I have two licence

That’s the beta phase reserved for the English and German.
we are left with a final unusable. awesome. just reinstall the older version 2009

and more still no full version 64bits
on this point, the developer 7zip should be more talented

really disappointed :mad:

you have to explain what exactly does not work.

spwolf

@AlexandrSh:

I have the same problem with crc error in Russia version of PA 11.50.61.
Windows Vista 32bits SP2

can you please tell us more on how are you creating these files. Is it spanning or?

spwolf

can you try selecting and compressing only several of these files, maybe it is some specific file/filename that is causing it to happen and that could help us isolate the issue.

I have tested with 50 GB archive and all went well. So it has to be a bit more specific.

thank you!

dragon57

I have more info, but no specifics that I feel confident will help.

I have tried zipping and splitting large sets of files, but none cause the problem except those from my VMware sets of files, and not all of those.

The problem appears to be related to zipping up large files that when finished, end up being near the end of the split boundary.

Example, I had eleven vm files that were all nearly 2GB in size. If I zipped them in dictionary name order, I could repeat the error, but if I renamed them and zipped in a different order, the problem did not exist. File name length seems to have nothing to do with the error.

Does any of this make any sense?

not really, but i will try creating VM files of same size and reproducing it like that :)

ivan

Sorry, I didn’t found an answer to one my question - does creating same ZIP archive with same files and size without spanning works fine?

dragon57

Yes, creating a zip with the same files without spanning works fine.

dragon57

Just fyi, the latest rc still has this same problem. ;)

spwolf

would it be possible for us to download those original files? Only way we can reproduce it (and fix it).

Maybe try with less files but same folder (smaller file size) and see if that works or not, if we can get smaller sample it will be easier.

thanks

dragon57

The file set is over 32GB, plus this is a VMware image that contains proprietary software. There is no way I could get it to you. I’ll try to come up with a repeatable scenario that causes the problem using smaller and different files, however the problem only seems to show up at the DVD sized split boundary.

dragon57

See if you can reproduce the problem using the below steps.

Download http://www.bertel.de/software/rdfc/rdfc.zip
Unzip the rdfc.exe file and put it in a temporary directory with at least 37GB of space.
From the temporary directory, create the test files by running the following commands in order:
rdfc “Windows Server 2003 Standard Edition.vmdk” 1818
rdfc “Windows Server 2003 Standard Edition-s001.vmdk” 2146304000
rdfc “Windows Server 2003 Standard Edition-s002.vmdk” 2145976320
rdfc “Windows Server 2003 Standard Edition-s003.vmdk” 2139947008
rdfc “Windows Server 2003 Standard Edition-s004.vmdk” 2141257728
rdfc “Windows Server 2003 Standard Edition-s005.vmdk” 2145583104
rdfc “Windows Server 2003 Standard Edition-s006.vmdk” 2138832896
rdfc “Windows Server 2003 Standard Edition-s007.vmdk” 2140471296
rdfc “Windows Server 2003 Standard Edition-s008.vmdk” 2137587712
rdfc “Windows Server 2003 Standard Edition-s009.vmdk” 2135818240
rdfc “Windows Server 2003 Standard Edition-s010.vmdk” 2144796672
rdfc “Windows Server 2003 Standard Edition-s011.vmdk” 2146172928
Highlight all the vmdk files, right-click and select parameters per the attached pic.

I then open the .zip file in Winzip and perform a ‘Test’. I get a CRC error. If you unzip with PA, you should eventually get either a CRC error, an erroneous password prompt, etc.

Let me know if you have any questions.

spwolf

extremly helpful, thanks a lot!

spwolf

this issue has been fixed in next release :-)

spwolf

and thanks a lot… huge help!

dragon57

That is so great. That had to be a hard one to diagnose and fix I bet. Great job and many thanks!

spwolf

@dragon57:

going through 5 GB archives with hex editor = awesome :-)

spwolf

You can re-download 11.60.12 from our website. Please check it out and see if this solved your issue.
We did not have a lot of time to test it out.

Thanks!

dragon57

Things are looking good. I tested two large directories that had problems before when zipped/split, but have no problems when zipped/split with the latest PA build. I’ll continue to keep a close watch on new zips going forward and let you know if I see a repeat of the problem.

Thanks!

spwolf

awesome. I will keep this thread open just in case :).

thanks
