Cannot mount storage drive in workstation

[Lynn Steven Killingsworth]

Dear FreeBSD -

I have broken my ability to mount my storage drive in FreeBSD installation.

I am still logged in as root since I have not installed the login manager  
yet to KDE4.  I think I managed to set my discs to mount under my username  
by setting the group privilege (wheel) to read/write.

Then I inadvertently shut off my display while my workstation was  
running.  When I restarted it I could not get my system to display again.   
So I had to shutdown my machine.  Then I rebooted a couple of times.   
However, I can no longer get my storage drive (not my system drive) to  
mount by selecting it in Dolphin when I start my workstation.

This is the message from Dolphin   
"org.freedesktop.Hal.Device.Volume.UnknownFailure: mount: /dev/ada1s1a:  
Operation not permitted"

My familiarity is the online handbook presently.

So can you tell me where to start?
