 I am not sure what image exactly you did use.
 I downloaded NetBSD-8.99.14.amd64-install.img.gz from the latest
 nycdn/daily/HEAD build and extracted it onto a USB stick.
 
 The disklabel looks like this:
 
 # /dev/rsd0d:
 type: ESDI
 disk: image
 label: 
 flags:
 bytes/sector: 512
 sectors/track: 32
 tracks/cylinder: 64
 sectors/cylinder: 2048
 cylinders: 1450
 total sectors: 2969600
 rpm: 3600
 interleave: 1
 trackskew: 0
 cylinderskew: 0
 headswitch: 0           # microseconds
 track-to-track seek: 0  # microseconds
 drivedata: 0 
 
 8 partitions:
 #        size    offset     fstype [fsize bsize cpg/sgs]
  a:   2967552      2048     4.2BSD   1024  8192    16  # (Cyl.      1 -   1449)
  c:   2967552      2048     unused      0     0        # (Cyl.      1 -   1449)
  d:   2969600         0     unused      0     0        # (Cyl.      0 -   1449)
 
 
 The ffs file system in partition a: fsck's cleanly and is mountable/usable.
 
 Of course (my umass stick is slightly bigger than the image) I a few logs like:
 
 sd0: 5304320 trailing sectors not covered by disklabel
 
 but that is harmless.
