Why yes, of course. Linux really doesn't enjoy writing to NTFS though, in fact it's really not a good idea at all. So yes you can "read" from 2 on 3, but writing will be a no-no for now. If you want to write to it, you might consider converting the "Shared" partition (2) to fat32 where linux has no qualms about writing to that.
Linux, RH in particular should have no problems (AFAIK anyway) with being able to see your Part 2 out of the box, but if it does, there are loads of threads on getting NTFS read support here, and probably a dedicated page for it somewhere that you could find from a quick search on www.google.com/linux
Does this answer your question, or am I missing something?
