For an explanation of why I use DiskWarrior: A power outage or system failure interrupts read and write processes, which can cause discrepancies between the file system directory and the actual location and structure of stored files. In an unjournaled file system, drives are in an unknown state after a failure, meaning that there is no record of their activity just prior to the shutdown.

Journaling accelerates the recovery time after an unexpected shutdown, significantly improving the availability of server and storage systems. When journaling is turned on on a storage volume, the server automatically tracks file system operations and maintains a continuous record of these transactions in a separate file, called a journal.

The operating system can use the journal to return the file system to a known, consistent state after a failure. This eliminates the need to perform a consistency check on the entire file system during startup. Instead, when the server is restarted, Mac OS X simply replays recent transactions in the journal, bringing the system up-to-date and resuming operations that were interrupted during the failure.
