I would get an annoying software pop-up with my old 1 GB Cruzer flash drive every time I would enter it in to the USB slot. Never figured out how to get rid of it, though. I think things like that are imbedded.

Doesn't happen with my newer flash drive, it's a Memorex 4 GB. I think flash drive companies finally wised up and decided that the users don't like to see any extra crap when they plug the thing in.
