Sorry about that... I was trying both cd0 and acd0, and yes, i know that
the disc is fine since I used to be able to dd from it. I also know that
the drive is fine  because I could dd from it back when  I was still
using slackware. This only showed up when I started with FreeBSD about 2
months ago.
