USB-data cable and Nokia 6230i

When I connect my Nokia 6230i to my computer it asks, if it is going to
be coonected like a usb-drive (I can't remember the word, because I'm
using the Danish version).
Aren't there any ways to say no to that everytime, without doing
something on the mobile phone (the mobile phone should do it itself)

And sometimes if I synchronize the mobile phone's contacts with the
computer's, I had to say okay, aren't there anyways not to do something?

I really hope on yours help
