Data Loss in Mac OS X due to Volume Header Corruption
Hard drive of Mac OS X can be divided in to several partition which is popularly known as volumes. In this Mac volume is generally formatted by using file system, which can be in the form of HFS+, HFS, HFS wrapper, HFSX. Entire information related to the Mac volume is stored in volume header. And if in this condition any damage occurs in it then entire volume becomes inaccessible and due to this severe loss can be suffered by the user.
User can use Disk Utility which is inbuilt utility of Mac Operating system; this utility is helpful in fixing many drive errors of Mac operating system. The main work of this utility is to check the integrity and consistency of hard drive and file system. But there may occur the situation in which user may suffer from occurrences of error message after running this utility.
“Volume Header needs minor repair
The volume Macintosh HD needs to be repaired.
