While using any operating system on the computer the hard drive errors are very common issues that most of the users encounter very oftenly. These errors generally occur due to the corruption of system files, critical data structure, meta data structures and so on. As these abnormalities happen with most of the operating systems so Mac OS X is also among one of them. Due to these issues the system may not boot, all the precious data becomes inaccessible and most importantly it may cause huge data loss situations. Recovering those data back is really a back breaking task in case the backup of the lost data is not available.
In order to resolve this issue Mac OS X system offers an inbuilt disk utility system to repair the hard disk and to coop up with such situation which is known as Disk Utility. But when you run this Disk Utility on the affected Macintosh disk, you may encounter below mentioned error –

"Checking disk "Mac OS X".
Checking "Mac OS Standard" volume structures.
Checking wrapper System file.
Checking "Mac OS Extended" volume structures.
Checking for locked volume name.
Checking extent B-Tree.
Checking extent file.
Checking catalog B-Tree.
Problem: Invalid B-Tree Header, 0, 0
Checking catalog file.
Problem: MountCheck found serious errors.
Checking catalog hierarchy.
Checking volume bit map.
Problem: Overlapped extent allocation, 4, 4430
Problem: Overlapped extent allocation, 4, 4430
Checking volume info.
Problem: Volume Header needs minor repair, 1, 0
Repairing the disk.
The volume "Mac OS X" was repaired successfully.
Volume "Mac OS X" had overlapping extents. Two or more files were accessing the same disk block. Aliases to the damaged files have been created in the folder "Mac OS X damaged Files"
Soon after this error message attempt made to access the disk will be failed and in order to extract the data from the affected Mac OS X hard drive you need to use efficient data recovery software like Undelete Mac File software. A this problem has occurred due to numerous reasons including volume header corruption, overlapped extent allocation, mount check error, volume bitmap corruption and many more so the disk will surely refuse to mount and in this condition recovering the data is the only way by which the critical data can be saved.
Launch Mac data recovery software
Now select volume for recovery of deleted data
Select file type
Now Start Scan
After scanning software recovers all deleted files including trashed one. From here restore files which you want at your specified location.
