Alsoft DiskWarrior for MacOSX offers scavenge mode

Just found the following hint from Rob Griffiths at macworld.com about Alsoft DiskWarrior:

DiskWarrior Scavenge mode: If you hold down the Option key in DiskWarrior’s window, the Rebuild button changes to read Scavenge. In Scavenge mode, DiskWarrior will look at the entire directory structure, not just those portions that are damaged. Note that the technique used in Scavenge is the same as that used in Rebuild; it’s just that all of the directory is examined. As such, you only need to use Scavenge when the disk’s directory is fine, but you suspect that there’s data missing. As explained in the DiskWarrior manual: Therefore, you do not need to make DiskWarrior scavenge the directory except when DiskWarrior states “All file and folder data was easily located” in the DiskWarrior Report, but you suspect that files and/or folders are still missing from the replacement directory.

BTW: even though DiskWarrior is still my number one tool for fixing problems with hard drives, don´t forget there is no support for Intel Macs and RAID volumes, yet.
