    Pat,
    
    Caution is the watchword with previews. Certainly using Encase preview is useful but you should be aware of a couple of possible concerns:
    
    1. If you preview and don't find anything, you *may* be prevented from continuing with analysis of that machine using a full image or even seizing the computer. (I think others have mentioned this problem)
    
    2. Text searching under preview does NOT work the same a text searching under image conditions. If a bad sector is located under preview, Encase appears to skip an entire cluster. 
    
    I like Encase and have been using it as an analysis tool since the Expert Witness days but I also use Safeback and a host of other tools for imaging and analysis. Encase is but one tool in my box and I'm always wary of *any* single tools results. Imaging is *always* preferable to previewing but, if your only option is preview, be sure to:
    	1. make copious notes
    	2. video the screen during the session
    	3. use non invasive previewing whenever possible.
    
    Good luck
