a CRC value for the file and saves the value in the Zip file. When you later extract the file from the Zip file, WinZip

Bad Crc Error

calculates the CRC of the extracted file and compares it to the value stored when the file was zipped. If these two CRC values do not match, the file that was extracted does not match the original file, and WinZip

Bad Crc Received

will display a CRC Error message. When the data in a Zip file is damaged, it may not be possible to extract all of the files from the Zip file correctly. Damaged data can affect the entire Zip file, multiple files, or just one file. Why CRC Errors Occur There are many possible causes for data damage. Among the most common is a transfer error when downloading a Zip file from the internet. Such an error can introduce invalid data into a cyclic redundancy check Zip file. Some other possible causes include exposure of media to excessive temperatures or magnetic fields, cross linked disk sectors, and mechanical problems with disk drives. What to do if a CRC Error Occurs The best solution to the problem of a damaged Zip file is to try to obtain another copy of the file. For example, use your backup copy of the file or get a new copy from the original source. If you obtained the Zip file by downloading it, then downloading it again will almost always solve the problem. A "Last Resort" for CRC Errors If you cannot download a new copy of the Zip file, obtain a replacement disk, or use a backup copy, you may still be able to recover some of your files, and even save portions of the files that are damaged in the Zip file. Here is the recommended procedure. Start WinZip and open the damaged Zip file Use the current available method for unzipping files to a particular folder In the Unzip dialog, select a target folder and click Unzip (XP users - Select the All files/folders in archive radio button and click Extract) WinZip will extract any undamaged files to the target folder. Each time WinZip encounters a damaged file, it will display a CRC Error message. Before clicking OK in the error message, open the target folder and look for the file; some portion of it will probably already have been extracted. Y

I downloaded a bunch of .zip files and I'm trying to unzip them viaunzip filename.zipIt 7zip works fine on all the files except for one. It's the largest winzip of the bunch at about 120M. When I try to unzip it, I get thisbad CRC 41041f89 (should be f5255afc)File-roller chokes too, but I'm guessing that it's just calling unzip behind the scenes.BUT....If I unzip it in windows using WinRAR, it works fine.I've read that unzip http://kb.winzip.com/kb/entry/41 commonly chokes on large files, but also that it would be fixed in version 6.0. But this file isn't even THAT big. Anyone know what might be going wrong? Maybe some options might help?

And that means, that the file is corrupted. Either it got corrupted whilst it was tranferred from the remote server to you, or it was already corrupted on the server. You have to download it a second time. If it still says that the CRC is 41041f89, the file was alredy in corrupt state stored on the server.

This could mean that there is an error with the unzip command, but I rather guess, that WinRAR did unpack the file, though there were errors (maybe was even able to correct them). I don't know, if that is possible with unzip, too, read the man page. Offline #4 2012-11-15 18:41:55 Lekensteyn Member From: Netherlands Registered: 2012-06-19 Posts: 181 Website Re: B

So the first attempt would be: zip -F broken.zip --out fixed.zip unzip fixed.zip And if that doesn't work: zip -FF broken.zip --out fixed.zip unzip fixed.zip share|improve this answer answered Jan 9 '14 at 22:22 Graeme 4627 add a comment| up vote 4 down vote DiskInternals ZIP Repair works perfectly under Wine it's saved me in the past. share|improve this answer answered Aug 30 '09 at 4:59 John T 124k18253298 2 You can also just extract the actual executable from the installer using 7-
