tar tapes

[Herb Chong]

i have a tar tape with a lot of files on it that i managed to overwrite the
first block with a tape mark.  i know that the rest of the tape is okay
and that the first file isn't too valuable.  how do i go about extracting
the rest of the data onto disk and rewriting the tape?
 
i know i need to find the first block of a valid file near the beginning
and feed everything from there on into tar via a pipe.  the dd command
should let me position correctly.  what should i be looking for to
identify this block?
 
any other advice welcome.  plese respond by e-mail and PLEASE DON'T ASK
how i managed to do this!
