The problem is that there is an apple ufs disklabel
at offset 7k of the partition.  This is probably leftover
from having had a previous apple ufs filesystem there
without having had it zeroed when you installed netbsd.

To verify this, you can
  hexdump -Cv -s 7168 -n 1024 /dev/rwd0a
and see if that starts with 'LABL' in the first 4 bytes.

The fix is to
  dd if=/dev/zero of=/dev/rwd0a bs=512 count=2 seek=14

Which will blow away the apple disklabel and allow
NetBSD to use its filesystem.

I hope this problem is not terribly widespread.
