	USB

	At the risk of cutting/pasting too little....

setup# 
MD5 (1Mcu) = f6886afdcdb7dcc6205d4e29649fbdb7
MD5 (1Mdu) = f6886afdcdb7dcc6205d4e29649fbdb7

valhalla# md5 1M*
MD5 (1Mcu) = f6886afdcdb7dcc6205d4e29649fbdb7
MD5 (1Mdu) = f6886afdcdb7dcc6205d4e29649fbdb7

	These were both with the disk unmounted. "cu" is partition
da0s1c, and "du" is partition da0s1d (Which is the partition I use
to mount)

valhalla# disklabel /dev/da0s1
# /dev/da0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  c:  8048502        0    unused        0     0         # "raw" part, don't edit
  d:  8048502        0    4.2BSD     2048 16384 28552

	Looks like matches all around. (And yes, I SHA256'd too)

	:-/ So now where?
