    Hi, Craig!
    
    I have ONE  suggestion to you!
    I graduated as electronic engineer(long, long ago!) but, I've never worked
    with electronics...but, again... it's kind of first love!
    
    If I were to do what you suggested... to make a forensics copy of any
    PDA...
    I would take one of those machines that enable you to make a 'real' copy
    of the mentioned 'chip'! That could be a EPROM machine (used on electronic
    labs). So you could keep the integrity of the original and deal with the
    copies.
    The final step would be to transfer ALL data to a non-erasable media
    (CDROM) compare both contents (chip and CDROM) and, finally proceed to the
    forensics analysis!
    I would never rely on another chip to make this kind of analysis, like the
    suggested below... that would be great for 'regular' backups!
    
    HTH,
