A good friend of mine uses MAC OS X and approached me saying his HDD crashed, but later learned that it didnt crash just the OS froze and it appears that some bits on the HDD were damaged enough so that the MAC OS couldnt read the HDD. He said you can look at the files on the HDD but just can copy them over. My question being is it possible to use Knoppix to recover some of these files from a MAC HDD?
