That's the guide I've been following too.
And I have made sure it was unmounted before I wrote the image. IIRC it
don't let you proceed if the drive is mounted anyway.
Well I tried that guide and it didn't work too. The problem is with
the dos file system. Follow the following link and it should work. I
made a few changes in the instructions that made it work. I used ex3
filesystem instead of dosfs.
