I just purchased a Lenovo x61s laptop with Vista Ultimate. I have noticed that when I have a thumb drive in the USB port, when I click on the remove drive icon I hear the blip and see the message that it is safe to remove the drive BUT the light on the drive remains on (it turns off on my other computer with XP). 1. Why is it doing this? 2. Should I trust the message that it is safe to remove the drive and ignore the light? Thanks.
