Well, here is the reasoning of why it SHOULD NOT work if you have a buffer/cache

etc etc etc.....

1)  What Norton is doing is loading all the clusters associated with data and
    simply moving it from one area to another.

2)  At times, there will be information that is left in your cache/buffer
    pertaining to a specific cluster.  When the cache/buffer gets full it
    dumps it to disk.  NOTE:  A single cluster can nuke SEVERAL files if
    "Lost"  

3)  After having done its moving of clusters and if there is a presence of
    a cache/buffer there is a very good potential of having some information
    still hanging in memory somewhere that has NOT been written to the hard-
    drive.  Norton after completion should give you a Red-Screen asking if
    you want to Reboot or Exit the session.  The recommended route is to 
    ALWAYS reboot.  Especially if you are in doubt of the status of your
    cache/buffer.  That is the reason for the RED screen

I hope this explains the whys and wherefores.....
