welll.. what does the message say ??
        - moreimportantly, do NOT type commands and hints people
        post in the list w/o knowing what it will do

- i assume you know to add the right options to find
- i assume you know to go find the program called buffer
- i assume you know the options for tar to read from stdin
        ( does "tar cvf /dev/std0 -" help ?? or 
        ( even "tar cvf /dev/std0 -T -" or
        ( lots of other permutations

yeah.. yeah about "assume" ...

if its written wrong ... it will barf at reading

it's written wrong if you do NOT hear a constant whine of the tape
vs the stop/rewind/start noises

of course not... and do you know why not ..

and that doesnt solve the problem of maybe the data is nto written
as you expected due to other problems
        - what kind of tape noises does it make when its writing
        and it should be a nice and steady/constant whine ...
