Mac operating system uses an efficient and reliable file system i.e. HFS (Hierarchical File System) to store and retrieve files. HFS file system was developed by Apple Inc for their Macintosh line of computers and later released an enhanced version which is HFS+. Compare to HFS, HFS+ is more advanced with various advantages like supports larger file names, long length block address and Unicode support for naming files and folders.
Whenever a file stored in HFS+ volume, file system allocates two components to stored file, which are Resource fork and Data fork. Resource is responsible to hold all the attributes related to stored file manipulation like menu items, code segments, etc and Data fork holds the actual data which user kept in the stored file.
Even though HFS+ is reliable and secure file system, sometimes users end up with losing Mac data due to various reasons. One of the main reason which leads to huge Mac data loss is corruption of allocation file. In case if you have lost your important Mac files due to corruption of allocation file, no need to panic, here is an optimum solution to get back your lost files. Using some efficient recovery utility you can perform Mac data recovery after allocation file corruption. Prior to discussing the recovery process let us see what allocation file is and how it gets corrupt.
Allocation file is one of the critical data structure element used by HFS+ file system to record the allocation block details of Mac storage volume such as whether they are free or in use. Allocation block is a group of one or more sectors and number of allocation blocks varies based on the size of HFS+ volume. Allocation file is similar to volume bit map but not same. However both perform similar functions but allocation file stored as a regular file and volume bitmap resides in the beginning of storage volume in a reserved space.
Sometimes allocation file gets corrupt due to power surge which leads to improper system shut down or operating system crash. Since it is the primary element to fetch the stored file in HFS+ volume, corruption of which make your Mac file inaccessible. Even though the files are there in storage volume, but file system fails retrieve which finally leads to huge Mac data loss. In order to get back your Mac files, you need to make use of some good Mac data recovery utility. They will scan the storage drive with a built-in advanced scanning algorithm and recover data from data fork.
Remo Recover (Mac) – Pro Edition is one such advanced Mac data recovery software which is developed by some Mac data recovery experts. This tool facilitates you to restore your lost files from inaccessible Mac volumes. Using this tool, you can restore more than 300 file types from HFS+ and HFSX Mac volumes. Irrespective of the reason for Mac data loss, you can use this utility to retrieve your data from formatted, partitioned, re-partitioned and inaccessible Mac volumes. Apart from hard drives this tool also supports recovery of deleted or lost files from external drives, USB flash drives, iPods and other storage drives which are accessible to Mac operating system.
