In the days of burning CD's I was always told that you should be quiet and not touch the PC when you were burning. In my experience there was indeed a correlation between noise and the success of burning. I'm not sure if this is a placebo effect or not, and if this also holds for reading CD's.

On the other hand, if you have a laptop with an SSD (which is non-mechanical) there shouldn't be too much sensitivity to vibrations, I think.
