Duplicating tapes accross the network

[Robert L. Howard]

I got this really great way to make duplicates of tapes between
machines.  I tried it out today, and it worked (or so I thought).
When I tried to read the new tape with:

	tar tf /dev/rst8

I got:

	tar: directory checksum error (0 != 40860)

The command to duplicate the tape was:

        dd if=/dev/rst0 bs=126b | rsh <host> dd of=/dev/rst0 bs=126b

This is SunOS (versions 4.0.3c and 4.0.2 on the two machines)

Anyone got any ideas.  I really need to copy this tape and I thought 
this would be a good way...

Thanks in advance
Robert
