Source : AlsoftOne of the leading application for repairing volume, Disk Warrior is now available in version 4.1 and finally brings support for Leopard as well as Time Machine as its Hard Links. Those links targeting files are hard-coded to preserve integrity and the possibility to access to different versions of the same named file. So repairing such links is not trivial, and Disk Warrior has to rebuild all file history to make Time Machine volume repair reliable.
The update will be free for owners of the version 4.0, or it will cost 49.99USD for owners of previous versions or 99.95USD for a first purchase.
