There is no other way to enforce the requirement that user A's data cannot  
be read by user B after user A has released ownership of the tracks and user B  
subsequently is allowed to allocate the same tracks.  Just don't start  
erasing all tracks in all data sets willy-nilly, or you may have DASD  
performance 
problems like you wouldn't believe.  Be VERY selective about  what you erase.
