i just bought a Kodak 16gb flash drive but when I plug it in my computer it is not showing up in my computer I know the usb port works because I have a 4gb flash the pops up every time. the flash drive is brank new and I have a windows 7 computer. any reason it would not be showing up on my computer? the weird part is that when I plug it in it makes a noise saying its connected just nothing is there
