When any software wants information from a disk, the Mac OS must go to the directory to find out where the information is located. Some of what is stored in the directory is the numbers, names, locations, types, and sizes of files and folders saved on the disk. The directory is an area of a disk used by the Mac OS to "map" all the information stored on the disk. The Macintosh filing system stores files by breaking them into allocation block-size pieces and writing them into unused allocation blocks wherever they are available.

HFS Plus uses allocation blocks sizes ranging from 0.5 KB to 4 KB.

The newer Mac OS Extended format, or HFS Plus, can keep track of over 4 billion allocation blocks per disk. Therefore, the larger the size of a disk, the greater the number of physical blocks in each allocation block, so that the total number of storage areas on the disk does not exceed the maximum of 65,535. The older Mac OS Standard format, or HFS, can only keep track of 65,535 allocation blocks per disk. An allocation block is a group of one or more physical blocks treated as a single storage area by the Mac OS. The larger the disk, the greater the number of physical blocks on the disk. The physical surface of a disk is comprised of many 512 byte storage areas called physical blocks.

Too often, they will incorrectly begin to "repair" your directory, and then give up when they realize that they have modified the directory to an irreparable state. Other products attempt to repair your directory one step at a time, ignoring the big picture of what is truly wrong with your directory, and risking file information that could be saved. This approach has a significant advantage that the others overlook. It fixes any problem with master directory blocks and alternate master directory blocks (HFS), volume headers and alternate volume headers (HFS Plus), volume bit maps, catalog trees, and extents trees.
