"Non-contiguous" simply describes what the term "fragmentation" really entails when you look at how a file is written onto a drive. Data on a drive is written into predefined blocks (predefined by the OS's file system) called clusters. If a file is written into clusters all adjacent to one another (contiguous) then it is not fragmented... > > How can my hard drive be 9.7 % non-contiguous if > > the ext2 filesystem is supposed to be anti-fragmenting? > > It's not _anti_ -fragmenting.

Of course, one is left without knowing what constitutes bad, too. The figure has much to do with average file sizes, percent use (space and clusters), and how often you change those files...
