> Does the corruption happen with different sources to tar/gzip/bzip2? I am now testing some other sources. It seems to happen with large files. > Does while archiving in verbose mode appear any error message? No, the archiving itself does not give any messages. The testing does. > What are the commands you run? $ tar cvzf mail.tar.gz Mail or $ tar cvjf mail.tar.bz2 Mail For the testing I use: $ tar tvzf mail.tar.gz or $ tar tvjf mail.tar.bz2 > Compression errors often occurs because of bad/damaged RAM.
