Had a play with encrypted ntfs directories and the ntfs 3.x extended system files. Adapted ntfs tng to cope with both and found a buglet in the process. Now all is happy.
Had a look at the compile warnings report for linux-ntfs 1.5.1 for powerpc. It seems powerpc use char == unsigned char which was breaking some signed char comparisons. Fixed that. Now need a powerpc person to test. (-;
