cdrecord not working in 9.1-RC1

[Fbsd8]

Subject was incorrect.

I keep getting this error msg from cdrecord.

Inappropriate ioctl for device. CAMIOCOMMAND ioctl failed.
Cannot open or use SCSI driver.

This is the console command I am using that generates the above error 
msg running on a 9.1-RC1 system.

cdrecord -v -eject /usr/FreeBSD-9.1-RC3-i386-diwsc1.iso

When I was running 9.0 os the above command worked fine to write 9.1-RC1
to cd.
