Data loss due to Journal corruption in Mac
Mac computers make use of journaling, to handle data loss situations arising out of virus attacks, power surges, malware etc. To deal with this data loss issue, both the HFS+ and HFSX file systems make use of the journaling system. Journaling basically means maintaining a journal file which contains all the information regarding each and every change that has taken place on each of the files on the hard drive. This journal file can later be used for restoring the computer to the last good known state.
However, there are circumstances in which, this journal file itself gets corrupted, due to unexpected reasons, and in such occasions, the file points at the wrong locations. This results in the file system getting corrupted, making the data inaccessible. Mac does provide an in-built fsck command to repair the damage, but if the damage is severe, you will have to make use of a good Mac data recovery software for recovery of data.
REMO Recover (Mac) Pro Edition software lets you recover lost/deleted data from both HFS+ and HFSX volumes with ease. This powerful Mac data recovery software not only lets you recover Mac files, but also lost or missing partitions. The software comes with a bootable CD, which can be used for data recovery, in cases where your system does not startup.
