It's better to find a whole disklabel.
According to the disklabel(5):
#define DISKMAGIC ((u_long) 0x82564557) /* The disk magic number */
My disk is set in dedicated mode, so:
# dd if=/dev/da0c bs=1 skip=1b count=4 | hd
4+0 records in
4+0 records out
4 bytes transferred in 0.022311 secs (179 bytes/sec)
