Interesting that you ask this question; I see no way to READ a filesystem 
blocksize. As a generalization, we're talking about filesystems along 
about the same size, with more than a 2:1 increase in reported space. I 
don't think there are that many "small" files in archive, but once tghe
blocksizes are known, it's not hard to check this out.
