Macintosh deleted file recovery after volume header corruption
Mac OS X system hard drive can be divided into partitions called as volumes. The volume may have HFS, HFS+, HFSX or HFS wrapper file system formatted. Each volume then includes a header part in which is stored important information such as size of volume, type of file system, starting sector address etc. from the above said fact utility of volume header is very clear and any kind of destruction taking place in it can make the whole volume inaccessible. Ultimately resulting into data loss, where Macintosh file recovery comes into use to fix the erroneous situation.
The inbuilt utility of Mac OS X system i.e. disk utility does the work of fixing hard drive volume problem. First it checks for file system consistency and integrity and repairs it accordingly. But, the major issue taking by here is inability of disk utility to resolute the issue and throwing error message as-
“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 its happening, process of disk verification and repair is stopped thereby with volume damaged as it was. For Macintosh undelete, error cause has to be found out first followed by the resolution. This happens due to mac volume header corruption, leading to unrecognizable volume and data inaccessibility. In mac system, volume header is 1 KB file system Meta data structure, corresponding HFS file system master directory block.
In order to sort out volume header corruption, hard drive needs format with recreation of drives volumes. After the operating system is reinstalled data restoration is carried out with using deleted Macintosh file recovery software or backup if available. Macintosh recover deleted files program is equipped in thoroughly scanning the drive by employing most sophisticated algorithms that makes recovery certainly possible. GUI feature further adds to it and it is compatible to work with Mac OS X 10.6 snow leopard as well.
Macintosh file recovery in thus useful in situation like mac volume header corruption and related issue.
