I "zeroed" the thumb drive as you suggested, but got the same result from 
`echo "p 2 0x0c * *" | fdisk -f - /dev/da0` as before.

BTW, that wiping of the thumb drive took over 14 hours! I should have 
thought to specify a large block size.

Here's a sequence of events, after dd'ing the Druid iso:

tripel# fdisk -p /dev/da0
# /dev/da0
g c1945 h255 s63
p 1 0x17 1 64259
a 1
tripel# echo "p 2 0x0c * *" | fdisk -f - /dev/da0
******* Working on device /dev/da0 *******
fdisk: Class not found
tripel# fdisk -p /dev/da0
# /dev/da0
g c1945 h255 s63
p 1 0x17 1 64259
a 1
p 2 0x0c 64260 31182165

Does this mean the second fdisk succeeded, despite what looked like an 
error?
