Files on flash drive don't appear

Hello,
My flash drive will make a pinging noise when inserted into the USB. However, nothing comes up for it in the removable drive. When I go into the disk management to use some of the solutions I have read about, it shows the drive F
but states "no media". If you right click on that drive's box, the "Change drive letter and paths" section will come up but is not highlighted and will do nothing when clicked on. When you go into the properties section, there is no area to write anything in as suggested in another post....HELP!
