    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.

    http://www.x-ways.net/winhex/index-m.html
    http://www.x-ways.net/forensics/index-m.html

    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.)
