File Sharing Problem

I'm trying to share a hardrive from my Macpro to my Imac. I have the sharing preferences turned on and have added the volume I want to share to the "shared folder" list. When I try to access it form my Imac I can see my mac pro but when I connect I can't see any folders.

I tried to share a folder from my Mac Pro boot drive and that worked !!!? I don't know why I can't share files from my other hardrives. Can any one help me?

By the way I'm using OS 10.5.8 on both computers.

Thanks

 

No one has any ideas?
