Looking for advice and tools?

I recently updated my NT4.0 to XP pro. I got a storage
problem, see detail.
Since Xp does not support modem, Nic card and CDRW (There
are no drivers available for them under XP), I decided
rollback to NT 4.0 instead of upgrading. There is a disk
that has 4 logical partitions C, D, E and F and two FAT32
(C, D) and two NTFS (E, F). I saw all of content that
original for NT existing under XP. Before I did rollback,
I did som dynamic extension to E and F. After rollback, I
can not see any format and content on these dirves.

Would someone please give me some advice or suggestion how
can I recover content on my disk?

Thanks lot!
