I've tried it against a floppy and the write
does fail, though there are a few ugly points
in there.

Hmm...  I wonder if the tape device driver you're
using doesn't consistently return an error for
a write past end-of-media?  I did find a couple
of places where failed writes were getting ignored,
but if the device keeps returning failure, then
bsdtar does eventually get the hint.

I'll have a revised patch for you to try soon.
(Let me know when you get back from vacation.)

Thanks for your help,
