Recover Lost Data from the Volume Header Corruption Situation

The Mac hard drive is designed to be divided into multiple numbers of partitions using HFS Wrapper, HFS, HFS plus file systems. The file system based volumes are managed in sectors. The initial sector is dedicated to the boot block, through which, the Mac OS X learns about the file system and boots. The second sector contains the volume header (in HFS plus) or the Master Directory Block (in HFS) which stores all the information about the particular Mac volume. Therefore, if there is any problem with the volume header or the Master Directory Block, Mac OS X cannot fetch information about the volume and the particular volume becomes inaccessible. Under such a situation, you need to take the help of Mac recovery to recover your inaccessible data back.

For any kind of system errors in Mac OS X, Apple has included a utility, named 'Disk Utility', which can help you locate the disk errors, checks the consistency of file system and repair them as well. Sometimes, while trying to repair the troubled disk/volume with the help of Disk Utility, error messages appear on the screen ceasing the operation in the middle. The error message may be read as below:

"Volume Header needs minor repair

The volume Macintosh HD needs to be repaired

Error: The underlying task reported failure on exit

1HFS volume checked

Volume needs repair"

With the above error message, all your data in the troubled volume remains inaccessible and you need to run any Mac data recovery software to restore lost data from the media.

Causes:

The error message is the result of the corruption to the volume header, for which the Mac OS X cannot be able to detect the particular volume and the data in it remained inaccessible.

Resolution:

As 'Disk Utility' fails to fix the issue, still you have another try by the command-line utility 'fsck'. The 'fsck' command is also meant to check the file system errors and fix them.

If the above means also fail to resolve the error, then the only possible way to resolve the problem is to format the media and make a fresh installation of the operating system. In such a case, you have to restore the data from a valid backup. However, in case, there is no valid backup available or there is certain problem in the backup itself, then, you can use any Mac data recovery utility to recover and restore all your seemingly lost data back.
