Reading tapes

[Chris Wayne SCONS]

     I'm looking for a program and/or technique that can read past EOF flags
on tape, for the sole purpose of reading the data that 'was' on the tape.
For example (common error), you do a tar -cv on a tape that has data...
With all of my knowledge, I'd say I'm SOL, but at the same time I know there's
got to be a way to retrieve the old data.  Any HELP will be appreciated.
