There are no generally available tools to fix this kind of problems.

I'd imagine data recovery companies like Norman Ibas have some in-house tools that could be used to do rescue operations on all kinds of NTFS systems, even striped. (as propably most of their customers run some windows variant)

How large are the filesystems?
If you really want to dig into it, and if you have the patience you could do a raw dump of the partitions to disk files and then depending on the structure of the data attempt to write your own tools to recover something.
(assumptions; the data must not be encrypted of course, and have some recognizable structure like plain text files...)
