DiskWarrior optimizes your directory for maximum performance. Directory optimization typically results in a 50% to 60% decrease in the time it takes programs to scan the directory and as much as a 10% to 20% decrease in startup time. Other programs may not provide the true directory optimization provided by DiskWarrior. 

DiskWarrior compares your old directory with the new rebuilt directory and determines if there have been any changes to the number or contents of your files and folders. It then lists any differences it finds in the DiskWarrior Report. You'll know right away what files and folders are affected by directory damage. The report lists the problems found by file, making it easy for you to see what files and folders you need to check in the preview.

DiskWarrior's patented preview feature lets you examine the files and folders on your damaged disk as they will appear after the directory is repaired but before any changes are made to the disk. This assures you that you will get the expected results before any changes are made permanent.

When enabled, DiskWarrior's hardware monitoring capability can notify you if your drive devices are in danger of failing. This notice can give you valuable warning, allowing you the opportunity to back up your files before the drive becomes completely inaccessible. Without such a back-up, your may be left with an expensive data recovery service as the only way to get your data back.

DiskWarrior verifies your rebuilt directory to ensure that it is error free. For protection from interruptions such as power loss, DiskWarrior uses a unique fail-safe method of replacing the damaged directory with the repaired directory. With DiskWarrior, you never have to worry about the safety of your files.

If there is a system folder on your disk, DiskWarrior will ensure that it is blessed. No more flashing question mark!

DiskWarrior safely rebuilds journaled disks. It also checks System and Finder files for damage, eliminates a common cause of system crashes by checking custom icon files for corruption, and repairs the wrapper volume System files caused when HFS Plus disks are initialized under Mac OS 9.0 - 9.0.4, allowing Macs with these disks to start up.
