I had already tried ad0.

dmesg revealed that the disk hadn't been seen at all. Perhaps I
plugged it in too late. Re-booting and re-plugging really early did
the trick (it was ad0, which was where the live DVD installed
DragonFly yesterday).

so fdisk -C ad0 says (slightly abbreviated):

cylinders=310101 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512 bytes.
Warning: BIOS sector numbering starts with sector 1
Information form DOS bootblock is:
The data for partition 1 is:
ssysid 165,(DragonFly/FreeBSD/NetBSD/386BSD)
        start 63, size 312581745 (152627 Meg), flag 80 (active)
             beg: cyl 0/ head 1/ sector 1;
             end: cyl 1023/ head 255/ sector 63
partitions 2 3 and 4 <UNUSED>

So where do I go from here?
