tar -xvM -L 85000 -f /dev/rsd1 -b 20  ???

Ideally, the device driver should correctly signal EOF, so the -L
stuff weren't needed.  OTOH, it's quite possible that the driver is
broken.  I fixed a long-standing bogon in the `fd' driver recently
that also resulted in a defunct EOF handling.  You should no longer
need the -L option to tar for multi-volume floppy backups these days.
