The problem with that is that the location where i call Drive.Mount is
inside a TreeView TestExpandRowHandler. I need to know if the
Drive.Mount call succeeded or not before i can return from that
handler (args.RetVal determines whether or not the row can be
expanded).

If i read your code right, it just defines a new delegate which gets
called at a later stage? (the code above doesn't wait for Drive.Mount
to report back)
