Mac Data Recovery after Journal File Corruption

Journalizing is a process in which data on Mac OS X is protected from any unexpected hardware and power failure. Most of the file system including HFS and HFS+ supports file system journaling and thus are less prone to corruption. However as all problems can’t be ruled out, serious consequences can result if the journal file gets corrupt for instance it can make Mac volume inaccessible and result in huge data loss.

So what is a Journal file?

A journal file is a system file, which stores all the vital information. When journaling is enabled on a volume, the file maintains continues changes to the files present on the Volumes, so that if your Mac system is abruptly shut down then this journal file will restore the volume back to its previous working state once the system restarts.

Follow the below steps to retrieve data from your inaccessible Mac volumes:

  • Use “fsck” command to repair your inaccessible Mac HFS or HFS+ file system. This command usually fixes most of the file system issues and makes your volumes accessible again. However usually journal file corrupts the Mac volume to an extent, that it cannot be repaired using command line utility like “fsck”
  • If the problem still persists, then format the disk using “Disk Utility” tool and restore your files from recent updated backup. If the backup of the lost data is not available or updated,then use a Mac Data Recovery application to retrieve your lost data after the corruption of journal file.
