I bought a Datatraveler G4 USB drive to put into my computer which I have windows XP installed. When I first put it in I and it began the download process, it gave me a warning saying it did not have a Windows signature and it could damage the computer. I stopped the installation, but after reading up on it it seemed like this was a standard warning and there shouldn't be any issues. I tried reloading the USB but not the computer is not reading it. One time it said it malfunctioned but was still not reading it. I tried a different USB in the same port and it worked. i tried restarting my computer but it is still not reading the USB, is there a way reset things so the computer accepts the USB and downloads it? Or a way to bypass the warning?
