OK, I'm not trying to give you a hard time, but that post doesn't make things any more clear. You really need to break that long run-on sentence into separate sentences.
For example, do you mean this?
"In disk mode you see nothing. When connected normally, the screen lights up. ..."
Or do you mean this?
""In disk mode you see nothing when connected normally. The screen lights up. ..."
I also really have no idea what you mean by "when connected normally" or "the ipod light fades as it does."
