I think you should try /dev/wd0e instead of /dev/wd0d. wd0e is entry
representing the NTFS file system, wd0d is the entire disk (including
some portions outside the NTFS partition).

You shouldn't need to write a disklabel: the kernel is already
generating a fake one that you can mount the disk with (which is what
it does for CD-ROWs for example) without a label written to the disk.

>From fdisk(8):

"NetBSD does not use the partitioning done by fdisk, instead it uses a
NetBSD disklabel saved in sector 1 of the NetBSD partition."

I.e. the disklabel can only be written to the disk if there is a
partition reserved for NetBSD. However, even without a disklabel the
kernel should generate a fake one (and it seems it is doing so for the
laptop) that can be used to mount the disk's partitions if any.
