Why Alsoft DiskWarrior Is the Only Answer

When you use DiskWarrior to rebuild your directory, it focuses on what you care most about on

your disk -- your data as it is stored in your ﬁles. DiskWarrior rebuilds your directory based upon

the data it ﬁnds in the original directory. If you have journaling enabled, the journal ﬁle may also

be used. DiskWarrior then uses this information to build an entirely new replacement directory

structure. This approach is similar to that taken by FileMaker with its databases and the Finder

with Desktop files. If you crash or otherwise close a FileMaker database improperly, the next time

you open that database, the ﬁrst thing FileMaker does is rebuild the database indexes (the

database structure) using the data in the database. When you rebuild your Desktop, you are

rebuilding the structure of the Desktop database. DiskWarrior takes these processes a step

further. When directory data is severely damaged, DiskWarrior scavenges the directory, ﬁnding

all the salvageable data. It then uses this data to build a new error-free replacement directory,

recovering lost ﬁles and folders as well as making it possible for the disk to appear on the

Desktop.

When other utilities attempt to repair your directory, they attempt to do so by “patching” the

directory structure. This method can result in sections of the directory being patched over and

deleted. Since whole sections of the directory can be deleted, this attempt at repair can cause

loss of directory data and thus loss of access to your ﬁles. Because of this, you should always use

DiskWarrior ﬁrst when you suspect directory damage on your disk. Otherwise, you risk losing

directory data (and thus access to your ﬁles). Successful directory rebuilding, repair, and

recovery by DiskWarrior is based on the quality of the directory data present.

If you have used another utility to repair your directory and you now have a directory with no

errors but missing data, you can make DiskWarrior scavenge the directory to ﬁnd the lost data.

This is the same scavenge procedure DiskWarrior uses to recover your data when it ﬁnds

directory errors, but it normally skips the scavenge procedure when the directory has no major

errors.

With DiskWarrior, there is never a risk of losing directory data and thus never a risk of losing

access to your ﬁles. DiskWarrior uniquely veriﬁes the replacement directory before it can be

written to disk to ensure that it is completely error-free. This also ensures that the disk will have

no problems when rebuilding is complete.

DiskWarrior compares the original directory with the replacement directory and determines if

there have been any changes to the number or contents of your ﬁles and folders. It then lists any

differences found in the DiskWarrior Report. You'll know right away what ﬁles and folders are

affected by directory damage. You can use this information to see what items you need to test or
