I always got quick and detailed answer to my questions on this list, which is very appreciable in this time of (small) trouble. (I feel sorry for the very poor english I demonstrated in the message I wrote this morning: I was in a hurry!)

As the other contributors join their voices to yours, I will replace the faulty disk ASAP. -- Thank you a lot, Michaël
