change step 3 to:

. xzcat BBB-eMMC-Flasher... ...img.xz | sudo dd bs=4096 of=/dev/sdc; sync

sync ensures that whatever is in the buffers actually gets written to the
disk.  The sdcard shouldn't even be mounted on the desktop while you dd
it.  At least with unity it will still dd properly but the desktop is not
aware and shows it mounted in it's previous state.  A desktop unmount at
this point is potentially harmful.

I wish there was a simple way to verify the image after you've flashed it
to the card -- does anyone know how to do this?

Cheers.
