Apple OS X Recovery For Corrupted HFS File System Volumes in Mac
HFS is a popular and powerful file system, originally developed for hard drives and floppy disks on Mac OS X computer. It is the predecessor of HFS+ (Mac OS Extended or HFS Extended) file system. Though, it is not used as a standard file system for earlier versions of Mac OS X operating systems, but it is nevertheless used on hard drives, optical disks, and removable storage media-supported by Mac OS X operating system. In some situations, the HFS file system quantity may become far away on Mac OS X operating system-based computers and you come across basic data loss situations. At this point, Apple OS X recovery becomes need of hour to get your valuable data recovered.
HFS divides your total quantity space into several equal-sized pieces, known as allocation blocks. The file system employs 16-bit fields for identifying particular allocation blocks and consequently the number of allocation blocks must be less than 65,536. A non-empty fork should occupy an inherent number of the allocation blocks. As the size of quantity and number of allocation blocks increases, amount of the allocated but unused disk space increases.
Allocation block is the smallest unit of disk space that is allocated to any file. The ‘allocated’ and ‘free for writing’ allocation blocks are tracked by the Block Allocation Map. In order to enhance the system performance, HFS replaced flat table structure with Catalog File that uses B-tree structure, which can be searched pretty quickly, nevertheless of the size.
All the data structures, which are used by HFS to store, manage, access, and manipulate data are very basic for working of the file system. If any of these metadata structures get damaged or deleted, file system may not work properly and data loss situations occur that put you in need of Apple Recovery solutions.
Data structure corruption can be the outcome of numerous reasons, including virus infection, improper system shutdown, user errors, system crash, and operating system malfunction. At this point, File recovery mac applications are basic to salvage business-basic data.
The Mac recovery software are specifically designed to thoroughly examine the problem storage media using progressive scanning algorithms and extract all lost data. They offer obtain and simple recovery with read-only conduct and high graphical user interface.
Stellar Phoenix Macintosh Data Recovery is the most efficient utility to insure absolute recovery of lost data in all possible scenarios. The software recovers lost Mac data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. It is designed for Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.
