Here is the only place I see that might be a problem, but it doesn't 
appear to be germain to your problem.  IF you have a cleaning tape 
in slot 6, then one would normally set lastslot to "5" which would 
prevent the inadvertant clean cycle during a "looking for the right 
tape" scan.  IF you don't keep a cleaning tape in slot 6 then I'd 
not even define cleanslot.  I don't know enough about your drive to 
be much help other than this.  My experience is with a 
Seagate/Campaq 4 slotter.
