Yes, thank you Frans and Andree for your help. We definitely found 
something.

If the journal is not clean then the mount is refused. This detection was 
added later, previously the journal cleaning was unconditional because we 
didn't know if it's clean or not.

So, I don't see a big problem here. The reliability of ntfsresize and 
ntfs-3g seems to confirm this. Nobody reported corruptions, in fact, people 
are finding bad hardwares (RAM, disk, cable) and softwares during usage and 
testing. Almost like ZFS :-)))

I still wonder why it doesn't boot. As I explained in my previous email, 
ntfsresize resets the journal unless the empty journal detection fails.

For me it seems it worked as it should have. If the journal is clean, 
then theoretically it's pointless to empty. If unclean then mount is 
unconditionally refused.
