This is the first I've heard of this. I have witnessed our staff at working plugging something in and having static discharge fry a USB stick, but I've never seen that happen while unplugging. I tell staff to touch the computer case before plugging it in first. When a user fries one I asked if they touched the case first and the answer is always "no". Dan
