Best to disable the in-kernel write support.  There was a warning it could 
corrupt a fs, unless you were overwriting an existing file with another file 
of exactly the same size.

Yes.

Have a look here, which explains what is needed for ntfs-3g:

PS.  I recall a case where a corrupted NTFS, I think it was on Win2000, could 
be read by the in-kernel driver.  Neither the native MSWindows OS could read 
it, nor the ntfs-3g.
