How to retrieve lost data from Mac HFS partition?

What's HFS?

Apple launched HFS or the Hierarchical File System as a fact of necessity to be worked with its newly developed 20MB hard disk for Macintosh operating systems. HFS replaced the old Macintosh File System (MFS), which was the original file system for the Macintosh operating system based computers.

Though the HFS file system has got several advance features in terms of performance, sometimes, while accessing volumes based on HFS file system, the volume cannot be recognized by the operating system and hence, the data in that particular volume becomes completely inaccessible. In such a case, you need to look for Mac data recovery software to recover your lost or inaccessible data.

The reason behind the corruption of the file system can be anything ranging from the unexpected system shut-down to virus attack, application malfunction or operating system crash etc.

In case of a possible file system corruption, you can use the 'Disk Utility' (The in-built utility in the Mac OS X) to check for the integrity of the disk and repair the damage. If 'Disk Utility' fails to resolve the issue, you can have another try with the 'fsck'(A command-line utility) to check the file system at the start-up and repair the damage.

Note: If the hard drive of the troubled Mac system is totally inaccessible, then you can either attach the drive with another working Mac machine or run the utilities from the system disk.
