Sysinstall and others do not detect disks

To Whomever may know the answer
I have run into an issue which I am at a loss as how to resolve. I am
attempting to add a disk to a running FreeBSD system, however no
application seems to be able to detect this new disk. This is a FreeBSD
4.4-RELEASE(GENERIC) system. The system boots off the primary disk
(ad0) without issue and was installed on this disk without issue.
However this disk is too small to be useful by itself and so I wanted
to add a disk. I read the appropriate sections of the FreeBSD manual
regarding adding disks however I have tried all the options presented
there ( i.e. sysinstall, manually compatibility mode, and manually
dedicated mode ), and none of these options want to detect the disk.
Sysinstall finds no disks whatsoever, including the boot disk. fdisk
give operation not permitted errors when trying to use it on the disk
device (i.e. ad1 ). I have used DOS fdisk to create a single DOS
partition. Even after this sysinstall, fdisk, disklabel and even dd
would give errors trying to read this disk.Sysinstall states that no
disks are present in the system, and fdisk, disklabel and dd all give
operation not permitted errors. I then formatted this disk with FAT32
and even mounted it with mount -t msdos /dev/ad1s1 /mnt/. Because of
this I do not believe that the disk is bad. I can't perform an fsck on
it because it has no filesystem.
If anyone has any suggestions as to where I can look for more
information or any advice whatsoever I would really appreciate it.
Thank-you very much for your time and attention
