i bought a flash drive about 3 to 4 years ago and it is a sandisk u3. i recently bought a new laptop with windows 7. now whenever i plug my flash drive in, a box will come up showing options. i will click u3 setup and nothing will happen. Then when i go to "computer" and look at the flash drive, there is nothing there. how do i format and setup my flashdrive or is my flashdrive just too old for windows 7?
