Well this just got a LOT more frustrating and interesting.  I made a
stick following those directions using a new stick...worked fine,
booted off of it...did some work on it...somehow the filesystem got
very corrupted in one of various things I was doing to it (I think it
was when I accidentially unplugged it before running a sync and
umount).  I figured it'd just be easier to start over and build it
again from scratch.  So...I try to newfs it ("newfs -U -L FreeBSDStick
/dev/da1s1a", and newfs fails with "cg 0: bad magic number" .  Now I'm
really getting pissed.  So...I run a dd ("dd if=/dev/zero of=/dev/da1
bs=1m"), and do the whole thing's the console output:

umm# dd if=/dev/zero of=/dev/da1 bs=1m
dd: /dev/da1: short write on character device
dd: /dev/da1: end of device
3830+0 records in
3829+1 records out
4016045568 bytes transferred in 4324.380202 secs (928699 bytes/sec)
umm# fdisk -BI /dev/da1
******* Working on device /dev/da1 *******

umm# bsdlabel -B -w da1s1

So now I'm getting seriously ticked off.  Anyone have any ideas what
the heck could be causing this?  This thumb drive was working fine
with FreeBSD!  I'm trying a dd on a thumb drive w/o specifying a block
size / BS...we'll see what that does...but I'm still open to
suggestions since I'm just about out of ideas.
