Macintosh systems are loaded with the utility that divides the hard drive into partitions called volumes. Volumes, as all might be aware of, are partitioned based on file formats like HFS, HFSX, HFS+ & HFS wrapper. This is where the header concept comes in to existence. Volume header keeps track of the sectors starting address, file system and information about the size of the volume. All in all it can be said that it is the most important component of the Mac volume. Even a slightest of corruption in header can lead to serious data loss. As the header of the Mac volume has all the information about the volume, if the header is corrupt the data on the drive becomes inaccessible.
Mac has a built in utility to recover from the situations like these like the header corruption . The utility is called “Disk Utility”. The disk utility checks for the integrity and consistency of the Mac volume & file system, and fixes the error and helps your Mac, to perform as it was earlier. But, this isn't the case always Disk utility fails to repair the header and this is when you face data loss situation.
What does “volume header needs repair” lead to?
Volume header corruption leads to fatal errors at the time of processing the data from your Mac volume. Your operating system will be left unrecognized.
Volume header corruption is the main cause responsible for fatal strange errors generated at the time of processing data from Mac volume. Damaged header leads to its non-recognition by the operating system. This happens as the meta-data structure is parallel to the HFS file system master block and all the data structures and the physical location of the data stored on the volume are stored inside it. This header corruption will also lead to inaccessible data files, this makes it impossible to diagnose the actual cause of the corruption occurred.

What error message can be displayed?
- Volume needs repair
- Error: The underlying task reported failure on exit
- 1HFS volume checked
- The volume Macintosh HD needs to be repaired.
- Volume header needs minor repair
How can you fix this error?
As the data files as well as the Mac OSX not accessible the only option you are left which is recreating the partition. Thereafter once done with this you need to reinstall the operating system. The header corruption issues will be solved after following these steps but the data will be lost to recover the data Macintosh file recovery software should be used. Mac data recovery software are capable of recovering deleted, corrupt data as well as it recovers data even from the formatted partitions too.
