A guy here hacked up a version to read/write multiple reels --
I've used it to dump a 300mb file system.  I've never had
a problem at 1600 bpi, but once, it failed to calculate the
length of a short reel at 800 bpi.  When this happened, I changed
the code so it always treats a reel as shorter than it really is.
So, it wastes a little tape, but has worked fine since then.
He started with a v7 version of tar that had been modified to continue
reading on errors.  Let me know if you want it.
