    I'm not sure if anyone's done this already- but it might be interesting to
    poll for everyone's top forensics tools.
    
    Keeping in mind that certain tools are better for certain tasks, what tools
    do you prefer, and why?
    
    
    
    ------ Original Message ------
    Encase is one of the many computer forensics tools out there - one of the
    better ones though.
    
    In terms of recovering data from a wiped drive that has been overwritten
    your
    chances are slim (unless you've got a very big budget and are very
    determined).  If you're serious about wanting to do it you need to find out
    more about microscopy - the technique that can be employed to recover the
    data
    based upon the magnetic signal strength on the drives surface..
    
    In addition to this when data is overwritten many times (eg the DoD standard
    of
    7) the chances of a technique such as microscopy recovering the data are
    very
    slim.  I could go on and explain why, but it's rather boring.....
