HFS (Hierarchical File System) is an advanced file system developed by the Apple Inc. It is the predecessor of HFS Plus file system. Along with the hard drives, it is also used on removable storage media. It is considered as a reliable and stable files system for Macintosh systems. However, some situations like accidental power failure, hardware failure, virus infection, and improper system shutdown, may cause damage to HFS and cause data loss. In such situations, Apple Recovery is required to extract lost data.

How to distinguish file system corruption:

You may have a corrupt HFS, if you encounter some of the below symptoms-

1) The files contain incorrect or garbage data.
2) The files are truncated or the data is missing.
3) The files disappear or alter the locations without any apparent reason.

Error messages indicating the probability of file system corruption appears in system log or the system console.

You experience problems in listing files in the directory or changing directories. System does not boot up and it becomes completely inaccessible. Particularly, if you face any of the above issues and can not identify the causes, you are recommended to check files for integrity using the fsck.

Locating and fixing HFS corruption using fsck:

In case of system failure, you need to restart the system and then run fsck utility to perform Apple Mac Recovery. Follow underwritten steps to check consistency of HFS file:

Unmount the HFS file using umount command. If system is running in single-user mode, you need not to unmount the file system.

Run fsck with -p option. It enables you to resolve various problems. If it finds any correctable problem, it fixes them.

If it does not solve the issue, check for other causes of the problem like hard drive formatting.

Hard drive formatting is the process of installing a new file on affected drive. However, it removes all the data from the drive and cause significant data loss. In such cases, Apple Recovery Software come for your rescue.

The Apple Recovery tools use high-end scanning algorithms to methodically scan the affected storage media and extract lost, missing, and inaccessible data from it. With read-only conduct and graphical user interface, the applications are completely safe and easy to use.

Stellar Phoenix Macintosh Data Recovery is the most efficient and comprehensive software to ensure absolute recovery of lost data. The software recovers lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. It works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.
