--disable-library links libntfs-3g into the binary statically. So it 
explains why you see no change. Complete static linking increases the 
overall memory usage which may not be fortunate in your case.

Polite wording for a fact :) Since the device is very CPU limited and 
ntfs-3g also isn't CPU optimized yet (optimizations for I/O makes more 
drastic improvements originally in the general cases), the busy-spining 
halves the performance in the worst case.
