Now perhaps you could help the list. When you reply with a (SOLVED) item, would you please leave the details that got things working for you. That way, the rest of us can often learn something also. For instance, I have an ATAPI DDS4 tape drive in an old system that I plan to move to FC4. Although the details would probably be somewhat different for me, your solution could well provide me with information and hints when I do start that project.
