you have to skip the 1st 32k:
dd if=/dev/nst0 bs=32k skip=1 | tar xvf -
I hope you used a norewind device
otherwize your screwd.
Run this shell script with the norewind tape device as argument,
it will tell you what's on the tape if any.
#!/bin/sh
TAPEDEV=$*
mt -f $TAPEDEV rewind
while mt -f $TAPEDEV fsf 1 ; do
dd if=$TAPEDEV bs=32k count=1 | head -1
sleep 1
done
good luck,

What laughter, why joy, when constantly aflame?
Enveloped in darkness, don't you look for a lamp?
