GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space. It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.

hfsdebug: A Debugger for HFS Plus Volumes

hfsdebug is a filesystem debugger for Apple's HFS Plus (hereafter referred to as HFS ) volume format. The term "debugger" may be somewhat of a misnomer for hfsdebug, because a key feature (rather, a limitation) of it is that it operates on an HFS volume only in read-only mode. Therefore, it cannot currently be used by itself to repair any defects in a volume, or to even write to a volume in any manner whatsoever. Nevertheless, hfsdebug is meant to be a useful tool in exploring HFS internals, as it allows you to browse, inspect, and analyze various aspects of HFS volumes. It can also calculate and display certain filesystem statistics. My original intent in creating hfsdebug was to quantify filesystem fragmentation under HFS .
