The original archive was created using the command:
 find . -print | cpio -ovBO NEW -HNEWC

analising the command;
    1. find . -print
            obtains a list of files in the current directory (NEW should not
            exist yet)
    2. cpio -ovBO NEW -HNEWC
            create a cpio archive, verbose, large block, output to file NEW
            using SYSV format (which does not truncate inodes for large file
            systems)

It is a very good possibility.... that some how before the archive was
created that the file NEW existed in the current directory, but
alphabetically NEW would be at the end of the archive, and there were heaps
of files that came before it....(look at the size of the archive)... they
were not extracted.

Nope!!
The extraction was broken with a CTRL-C after about 10 seconds purely to
include a -v option, to list files. (as previously stated)

But I will restore the file from tape backup and do the following:

cpio -itBI NEW | grep NEW &&  echo "yes you're right" ||  echo "no your
wrong"

I'll keep you posted!
