I think you need to open the *c device to get raw device I/O.
In your case that would be /dev/wd0c.
And btw, another part of your problem could be that FreeBSD
has used ad, not wd, for ATAPI devices access for some time;
unless you're running < 4.0 (or hmm, somebody correct me: when
did the wd -> ad transition take place?), try opening /dev/ad0
or /dev/ad0c.
Both 'head -c 512 /dev/ad0 | hd' and 'head -c 512 /dev/ad0c | hd'
work for me, on 4.2-stable (4.3-RC from March 25th).
G'luck,
Peter
