Graphing a Disk Directory Chapter 2: Using DiskWarrior 41

4) Click the Graph button.

A progress dialog will appear and, after a brief delay, it will be replaced with a window

containing the graph.

Note: In order to graph a disk, your display will need to be set to thousands of colors. If it

is not, you will be shown a message that will ask if you want DiskWarrior to change this

display setting. Then, when you close the graph window, DiskWarrior will return your

display setting to its previous setting.

5) If you wish to save a copy of the graph, choose “Save” from the File menu.

A Save dialog will appear. Pick a location and name for the saved graph.

Understanding the Graph

Each part (node) of the directory is assigned a color along a gradient between white and dark

blue depending upon its optimized position. The graph of a perfectly optimized directory is a

perfect gradient from white to blue. Fragmentation interrupts the gradient. The more distant a

fragment is from its optimized position, the greater the difference between the color of the

fragment and the color of the same position in the example optimized graph.

Directory optimization is the process of defragmenting and packing nodes. Defragmenting

makes the physical order equal the linked (logical) order. Packing combines nodes that are not

full so you end up with fewer nodes. The graph does not indicate whether the nodes need to be

packed. It would take a completely different representation of the nodes to indicate that

information. However, fragmentation has a far greater impact on performance. It is much worse

to jump around from one part of the directory to another than to read some extra nodes.

The more nodes that are out of order and the more ﬁles and folders are out of order, the more

impact you'll see on performance. Other utilities may not optimize your directory the way

DiskWarrior does.
