I have a SanDisk Cruzer 2GB memory stick that has quit working. When plugged into the USB port it lights up but it is not reconized. I have tried plugging it in mutiple computers ( PC and Mac). Other memory sticks work in the USB port so I know it is working. When I last removed the stick when it was working I never could get a "safely remove hardware" icon so I just unplugged it. Did I fry it when I removed it? If so, why does it light up when plugged in? I have searched multiple forums and have not found anyone who has stated this problem. Thanks for any suggesstions.
