When wbak'ing more than once to the same cartridge tape, you must
add the '-no_eot' option to all but the last wbak.  This option
suppresses double end-of-tape marks for cartridge tapes.  The
first wbak should be

          wbak -dev ct -f 1 -no_eot //blah/blah/blah

and the second one should be 

          wbak -dev ct -f cur //blah/blah2
