When Should I Use DiskWarrior?

Obviously, you should run DiskWarrior when you suspect that there is directory damage on one of your disks. Directory damage can result in a disk not mounting (not appearing on the desktop when the computer is started), missing files or folders, an inability to move or copy files, or crashes when files are used.

The best use of DiskWarrior is for preventative maintenance of your disks. Many forms of directory damage do not manifest themselves until long after the damage has actually occurred.

You can prevent this damage from escalating by running DiskWarrior on your disks regularly - we suggest at least once each month. DiskWarrior will rebuild your disk directory, eliminating all existing directory damage. The directory DiskWarrior creates is also optimized for maximum directory performance, and this will speed up the performance of your disk.
