Good luck. Reiser is not going to be a well supported os for recovery tools.
Surpisingly, googling for "computer forensics reiserfs" turned up more
hits than I expected.
The first 2 look very promising: WinHex and X-Ways Forensics.

WinHex in particular is a good tool for Windows based problems, I have
no exp. with it and Reiser.
I've never heard of the X-Ways Forensics tool before. (And forensics
is what my company does.)
