I assume this question has long since been run into the proverbial
ground, but I just ran into the problem. I have been archiving
comp.sources.unix, comp.sources.misc, alt.sources, and
comp.sources.games, plus all sorts of patches ofr everything. Anyway, I
tried to archive v17 of comp.sources.unix, using
tar cvf /dev/mt/rmt4 unix.src/v17
And it worked perfect. Notice, I used rmt4, this was so I could then
follow it up with v06 of games. Anyway, I archived the games next, and
then got nervous (I tend towards nervousness in unfriendly environments ;-).
When I tried to check the first file, it worked fine with.
tar tvf /dev/mt/rmt4
But when I did this command again, it would not give an index for the
games sources. WHY!!!
(John , can you help on this one??)

WHY!!! 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" -John
