I can help you through recovery using Ubuntu Linux; with different RAID5 configurations. But that's a quite complicated route and would likely require you to open SSH access for me. It also wouldn't work if there is any damage on your filesystem; though it would be able to correctly access the virtual RAID-array as the problem might be RAID-layer related.
However, perhaps i'm not too optimistic about your recovery chances with this route. There are some recovery programs available on Windows that can both recover files from corrupted NTFS filesystem, as well as access the NTFS filesystem on a virtual RAID array; so the recovery program is accessing separate disks and creates a RAID array only for itself. This also requires you to use AHCI/IDE mode during the recovery. This may have a higher rate of success than the Linux/BSD recovery route. However, none of the good recovery apps that can do this are free, as far as i know.
Last thing i want to add, is that any action you perform right now may be destructive and may cause permanent corruption/inaccessibility. So if you're really sensitive about the contents, i wouldn't risk connecting them to windows ever again and go for 100% read-only recovery techniques.
