Chapter 1: Introduction 9

not updated at all, that directory is considered damaged. This damage is normally limited to only

a speciﬁc area of the directory. Therefore, it’s quite common for directory damage to remain

undetected until long after the damage actually occurred. Also, if any portion of the directory is

overwritten by an errant program that inadvertently writes its own data, the directory is damaged.

When the Mac OS attempts to use the incorrect directory information to read or write

information on a disk, an error will occur. This error may be very minor and go unnoticed. It

might cause a kernel panic or crash. Or, worst of all, the entire contents of your disk could

become inaccessible.

Note:

Many people mistakenly think that the invisible Desktop files are a part of the

directory. They are not. The truth is that the Desktop files are maintained by the Finder. They

contain a list of your applications and the folders in which they are located (for quick

opening), and the icons and “Get Info” comments of all ﬁles. DiskWarrior does not “check”

or rebuild the contents of the Desktop files. Rebuilding the Desktop files will not repair any

directory damage and may even worsen any existing damage.

How Does Directory Damage Occur?

The continued accuracy of information in the directory depends on the ability of the Mac OS to

perform ALL of its update and maintenance operations without any unexpected interruptions.

Also, to help speed up many Mac OS computer operations, important pieces of information are

temporarily cached in memory instead of being immediately saved to the disk.

Common types of unexpected interruptions are kernel panics and crashes, power loss (lights

ﬂicker), turning your Mac OS computer off without using the proper “Shut Down” procedure,

and pressing the “RESET” button. Depending upon the exact moment of the interruption, you

stand a good chance that your directory was either not updated correctly and/or some

information had not been saved to the disk. You now have directory damage and/or information

loss.

Another way that your directory can be damaged is if an errant program inadvertently writes its

own data to the portion of the disk that is reserved for the directory. If this occurs, then your

directory data has been overwritten and may be permanently lost.
