Sending this out to Brian and the list. He forgot to cc list.

Hi Brian,
This is an experiment. I had a external USB drive lying around (close
to full), so I'm playing with it. I also had a 2.1GB image from an
earlier experiment, so I used dd if=image.img of=/dev/sdc1 bs=1M but
what I want to figure out is if the data past 2.1GB is recoverable.

Hope this clarifies.
