Unable to extract audio cd tracks

[David Demelier]

Hi,

Reading this http://www.freebsd.org/doc/handbook/creating-cds.html I 
would try to extract my files from my optical drive. (I don't have 
atapicam but if I understand well it's only needed for cdda2wav)

markand at Abricot ~ $ sudo dd if=/dev/acd0t01 of=track1.cdr
dd: /dev/acd0t01: Invalid argument
0+0 records in
0+0 records out
0 bytes transferred in 0.026221 secs (0 bytes/sec)

do I really need atapicam even if I directly read from the device?

Kind regards,
