I waited a few days before I posted this, but ever since the ScanDisk problem has been corrected, removing BlackIce, this computer has been shutting down with out a problem, which was what brought me here in the first place. Also found that the only way for me to stop BlackIce from writing to drive was to use the "stop BlackIce engine" command THEN exit the program.
