Recover Corrupted .gz file

Yes, you can try to recover a .gz file, but expect to have large data loss from the middle of it.

First, make a copy of the file and work only with the copy.

Make a

gunzip  < arquivo_com_erro.gz > arquivo_saida

And your exited file will have everything you could recover until the first crash.

To recover what's after the crash, one method is compiling the gzip program with a few more lines of code. For this, I suggest following the recommended link , and it will take time and it will not be easy)
