Ok, my point was that 3.4% is a low number for a long used system, but, for education sake, what is the difference between Windows' "fragmentation" and Unix's "fragmentation"? I believe that a "fragmented file" in common usage refers to a file which is not stored continuously on the drive - i.e. it occupies more than one continuous region. How is UFS fragmentation different than fragmentation on other kinds of file systems? UFS has cylinder groups, blocks and block fragments. Obviously, a file larger than a cylinder group will get fragmented to spill over to another cylinder group. Block fragments only occur at the end of files.
