Data Recovery on HFS/HFS+ File System

When deleting a file, Mac OS X deletes system BTree+ records describing the file. Therefore, it is hard to recover such file directly. Those records may remain in:

1. The swap file (if the deleted file has been deleted recently).

2. In the journal (if the HFS+ journaling is on, and the deleted file has been CREATED recently)

Actually, if a file has been deleted, chances that the records would be found are small. To greatly increase the chances to recover deleted files successfully , you may actively use scanning with enabled Raw File Search .

Note: All above is correct for intentionally deleted files. In case of a corrupted file system, HFS/HFS+ can be recovered quite successfully.

When saving files with HFS+-specific attributes (resource fork, finder info, etc.) to a non-HFS+ disk, Restorer Ultimate saves them in the so-called AppleDouble format. When they are copied to an HFS+ disk under Mac OS X, those attributes will be automatically restored.
