Normally this means that the decompressor actually recognized my data as being in the right format and decompressed it, but when it compared the result to the expected length as indicated by the CRC, they weren't the same. However, for comparison reasons, I actually do want to see the output to see if it's just a gzip recovery toolkit concatenation issue (which should be relatively obvious if the decompressed output isn't gibberish but just in the wrong order). java gzip decompression share|improve this question edited Oct 31 '12 at 1:13 alphazero 21.8k32124 asked Oct 31 '12 at 0:53 user1777900 4391719 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote You said "unzip", but the question says "gzip". Which is it? Those are two different programs that operate on two different formats. I will assume gzip. Also the length is not "indicated by the CRC". The gzip trailer contains a CRC and an uncompressed length (modulo 232), which are two different things. The gzip command will decompress all valid deflate data and write it out before checking the crc. So if, for example, I take a .gz file and corrupt just the crc (or length) at the end, and do: gzip -dc < corrupt.gz > result then result will be the entire, correct uncompressed data stream. There is no need to modify and recompile gzip, nor to write your own ungzipper. gzip will complain about the crc, but all of the data will be written nevertheless. share|improve this answer edited Nov 1 '12 at 3:29 Greg Hewgill 511k1088801044 answered Oct 31 '12 at 5:13 Mark Adler 35.2k63773 add a comment| up vote 0 down vote As far as I'm aware, the CRC che

When you add a file to a Zip file, WinZip calculates a CRC value for the file and gzip stdin invalid compressed data--format violated ubuntu saves the value in the Zip file. When you later extract the file from the Zip file, WinZip 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 will display a CRC Error message. When the data in a http://stackoverflow.com/questions/13149751/force-gzip-to-decompress-despite-crc-error 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 Zip file. Some other possible causes include exposure of media to excessive temperatures or magnetic fields, cross http://kb.winzip.com/kb/entry/41 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. You can copy the partially extracted file to another folder and then click OK in the WinZip error dialog. When you click OK, the partially extracted file will be deleted from the target folder,
