How to Recover Data from Mac After Journal File Corruption?

A Journal file is an in-built program of HFS+ file system “also known as Mac OS Extended (Journaled)” that maintains all the changes done on your system or disk even before the changes get saved on the drive. When journalizing is enabled on a disk, the journal file helps to restore the disk to its healthy state after facing sudden power failure, malware attack, etc. Journal file tracks changes that happen within the system which are not yet saved or complete. If the system or OS fails, Journal file helps in completing the incomplete or abruptly terminated task by taking the recently tracked changes.However, if the Journal File itself is corrupted, you cannot restore the interrupted tasks or events.
