final cut x will not recognize my external harddrive

Everything was working fine until I updated to 10.0.6. Now FC will not see my external HD as a HD, when I tried to import it has it under the camera finder instead of the drive finder. None of my past project are showing in the events or project areas. I tried to go to the FC folder and open it from there, it will open FC and show the projects for the first few sec while it loads, then everthig is gone.
