You'll need to use the program ftmt which comes in ftape-tools to
retrieve the first few segments (4 or 6 I think - starting from
number 0) using:
ftmt -f /dev/rawft0 getseg 0 > segment-0
ftmt -f /dev/rawft0 getseg 1 > segment-1
etc.
Unfortunately, I don't see an option in ftmt to write this to another
tape; it looks like you'll have to make a small program (can someone
correct me on this?)

Yes, this also. As mentioned in my last email (just now), if the
destination tape has bad sectors where the source tape doesn't,
there's nothing you can do to copy the tape bit for bit. Adjusting
the data isn't so easy, as segment sizes may differ, so the volume
table may be different, and as some of the archive has segment
alignment requirements, the whole dump will look different.
