It might be some copy protection and it might be not.

Please, read ata(4) and atacontrol(8) manpages to
learn how to tweak different options of ata driver. If
that doesn't help at all, try compiling a custom
kernel with "device atapicam" (make sure SCSI
support is also present). This will give you an
alternative interface to your drive.


Good luck.
