Fix Volume header corruption – “volume header needs minor repair” error
Macintosh operating systems are provided with the utility as such it is possible to divide hard drives into partitions called as volumes. Mac volumes are formatted based on file formats i.e. HFS, HFSX, HFS+ & HFS wrapper. Volume header is an essential component of volume which includes all information such as its size, file system, sector start address and furthermore. Containing all these critical information, header constitutes an essential component of the system. This is why in case the header gets damaged, the entire volume is damaged and thus made inaccessible, leading to critical data loss situation.
Mac system's inbuilt utility i.e. disk utility is meant for fixing mac hard drive volume header that are quite frequently occurring. The tool works & fixes encountered errors by checking the consistency and integrity of file system and drive volume. However, this may not be the case always and disk fails to do volume header repair.
In a particular situation as this one, when fixing damages, the below given error message may be received –

What leads to ‘volume header needs repair' error?
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 and thus the errors as such.
Mac volume leader is 1 KB file system metadata structure, parallel to HFS file system Master directory block. Volumes significant information, data structures and physical location are all stored inside it.
How to fix ‘invalid volume header mac' error?
In order to resolve this very problem taking place in your mac system, it is essential to format hard drive, recreate hard partitions i.e. volumes and thereafter reinstall the operating system. Once this has been done volume header corruption issues have been sorted out and data restore from backup could now be done.
The other option would be using Macintosh file recovery software for restoring the lost, deleted, inaccessible files in addition to data files from formatted mac volumes with ease and efficiency.
