Linux NTFS support had a sad history of problems, and it was almost
given up until a new rewrite recently was included in mainline. I am
not sure of when that happened, it may have been as late as 2.6.13.
Due to all the problems, the previous version was crippled to write
only inside existing files, that is, only when it was not necessary
to alter the metadata structure. That means no new files, no renames,
no moves, no append, not even delete. It was essentially a read
function turned ont a write.
Due to license fears and other issues, distributions may or may not
include the new ntfs code in their kernels.

I don't know what error number the old ntfs would use to say "no"
to unsupported operations.

By the way, I saw you got an answer from Peter Breuer (Hello Peter!)
but for some reason it was not threaded with your post. It seems to
contain approximately the same information as I give you here, but in
a different style. If you haven't read it yet, his posts are best
read wearing red glasses and a crocodile skin. If you already read it,
be honored, it is much more friendly than many others. He appears
(in my view) to be working hard to become more friendly and informative,
although we may differ in our interpretation of pedagogical issues.
Good luck,
Enrique
