The problem here is that NetBSD really wants a NetBSD disklabel on the disk.
It doesn't find one, so it can't access any partitions.  That's why you
get the "no disk label" message.

You might try using /dev/sd1d, since that's by default "the whole disk",
rather than "the first parition".  There is a slightly weird technique for
putting a BSD disklabel on a MS-DOS only disk.  Check the mailing list
archives for it.

I believe that in -current, the disk driver was changed to emit a default
disklabel so that you don't need to do this anymore.
