This way the system is reinstated to the working state faster. All that operating system has to do is to refer to the “Journal” and get the records of all recent transactions that happened prior to the system failure. With journaling feature enabled, a lot of time spent on consistency check can be saved, as with journaling is done already, the need for consistency check is eliminated. More the data present on the system, more time it takes to reinstate the machine to its working state.
FORMAT EXTERNAL HARD DRIVE MAC JOURNALED UPDATE
In an event of a power failure or any other disaster which prevents this update to the file system directories, the operating system will take an unexpected amount of time to start again since the system will have to perform a consistency check that requires it to go through the entire file system block by block. However, this process results in write overheads it is worth it. This way a record is maintained of the current transactions, that happen. Additionally, it also marks the action as completed in the journal once the task has been executed.

All of this happens automatically on OS X. These entries are maintained in a special type of data structure called “ Journal”. When the journaling is enabled on Mac, it keeps record entries of the changes to the files present on the disk. Journaling is a Mac OS X feature that is extremely helpful in protecting the system against the problems that arises due to power failures, hardware failures and directory corruptions.
