Geli Encrypted DVDs

[miggir]

Hi,

After following -good enough, i hope- previous guidelines in this list
and freebsd-questions, i still can't attach the cd/dvd.

novastorm# geli attach -r /dev/acd0
Cannot read metadata from /dev/acd0: Input/output error.

novastorm# geli dump /dev/acd0
Cannot read metadata from /dev/acd0: Input/output error.
Not fully done.

novastorm# ls -l test.iso
-rw-r--r--  1 root  wheel  104857600 Jun  7 19:47 test.iso

novastorm# diskinfo -v /dev/acd0
/dev/acd0
        2048            # sectorsize
        104861696       # mediasize in bytes (100M)
        51202           # mediasize in sectors

And for the image's memory disk:
novastorm# geli dump /dev/md0

I don't know if it's relevant, but just in case, i created the image
file with:

novastorm# dd if=/dev/zero of=test.iso bs=1m count=100
novastorm# mdconfig -a -t vnode -f test.iso -S 2048 -u 0
novastorm# geli init -l 256 -s 2048 /dev/md0
novastorm# geli attach /dev/md0
novastorm# newfs -O 1 /dev/md0.eli

and wrote it with # burncd data test.iso fixate

So assuming i didn't do anything wrong yet... what could i try now?
