I've just recently brought a FreeBSD install online.  Everything is working
fine, but now I want to add an additional SCSI disk to my file system.  I've
been trying to follow the procedures outlined in section 10.5 of the FreeBSD
Handbook.  Here are my attempts and results:

When I try running sysinstall, I go "Configure" and then "Fdisk".  After
selecting "Fdisk", the following message appears:

	No disks found!  Please verify that your disk controller is being
	properly probed at boot time.  See the Hardware Guide on the
	Documentation menu for clues on diagnosing this type of problem.

I know that the drive in question is detected at boot because the kernel
displays information about the disk whenever the system is coming up.

When I try running "dd if=/dev/zero of=/dev/rda1 bs=1k count=1", I receive
the message "dd: /dev/rda1: Operation not permitted".  I thought that maybe
I should replace rda1 with da1 because my drive is /dev/da1.  When trying to
run "dd if=/dev/zero of=/dev/da1 bs=1k count=1" I get the message "dd:
/dev/da1: Operation not permitted".

If you go to section 10.5.2.2 in the Handbook and then follow either of the
two command sequences I get the same results.  I also noticed that in the
Handbook the commands used use both rda1 and da1.  Is that normal?  I don't
understand why you would use two different device names?  As I understood
it, the prefix r- is for removable media.  Am I wrong?

The following is an excerpt from the /var/log/dmesg.today file:

ad0: 515MB <WDC AC2540F> [1048/16/63] at ata0-master PIO3
ad1: 1549MB <WDC AC21600H> [3148/16/63] at ata0-slave WDMA2
ad2: 4112MB <WDC AC24300L> [8912/15/63] at ata1-master WDMA2

And, yes, I was running sysinstall and the dd commands as root.
