Nope.

These days I expect most removable media to be MBR-partitioned, and to
get a faked-up disklabel from that. The SD card I used above ends up
with:
5 partitions:
# size offset fstype [fsize bsize cpg/sgs]
d: 246016 0 unused 0 0 # (Cyl. 0 - 120*)
e: 245919 97 MSDOS # (Cyl. 0*- 120*)

Yeah. I don't expect that to be terribly relevant to this problem, though.
