I had a bad experience doing this accidentally. I mistakenly left my laptop in my car overnight in the dead of a Boston winter...and the next morning my HD, which has moving parts, did not like it one bit and made creaking noises. I realized what had happened and let it warm up for a while on my lap, then restarted and it was fine. Perhaps mine was just way to cold and there is a mimimum temperature one could suggest?
