- in your documents folder, create a new folder, call it "volumes" or "drives" or whatever. You can also assign a custom icon to this folder using get info.
- open the folder and open a separate finder window (command-N). Select the "computer" icon at the top of the toolbar to open up the hard drive icons for each drive or partition.
- select a drive icon and then holding down option-command (apple), drag to create an alias in the "volumes" folder. Do this for each partition/volume.
- Drag the folder to the dock. Voila! now you have a hierarchical menu of each drive.
