Try the tar command a THIRD time.

>(John , can you help on this one??)

If you are using the Everex only driver (as opposed to the combined
archive/everex driver) then you may have this problem.  That driver
did strange (reas as "bad" or "wrong") things with the no-rewind devices.

This is what (I think) is hapening:

The tape should look like this (with the "^" being the current read pointer):

     [comp.unix.sources.TAR]<EOF>[comp.sources.games.TAR]<EOF><EOF>
     ^
	tar tvf /dev/mt/rmt4
	"Prints out index of archive"
	
     [comp.unix.sources.TAR]<EOF>[comp.sources.games.TAR]<EOF><EOF>
                           ^
	tar tvf /dev/mt/rmt4
	"Prints nothing because it sees an EOF"

     [comp.unix.sources.TAR]<EOF>[comp.sources.games.TAR]<EOF><EOF>
                                 ^
	tar tvf /dev/mt/rmt4
	"Should print out a TOC of the second archive"
