Can you describe your issue in any greater detail than this?
You are clicking on the little upward pointing white arrow at the left most end of the system tray in the bottom right hand corner of the screen but you do not see the icon?
Or you see the icon there, click it and nothing happens?
Or you see it, click it and get an error message?
I would ask how up-to-date your computer is with windows updates, because I think there have been a few recently related to usb drives, and a few a few months back also. Do any of these sound relevant to your issue:https://support.microsoft.com/en-us/kb/3013172https://support.microsoft.com/en-us/kb/2993843
If they are not installed already you might consider installing those particular updates.
If you look in "my computer" (that's what it was called once, it might be called "computer" or "this pc" on your machine) you can see your hard-drive listed, you can see your cd-dvd drive listed and you should be able to see any inserted removable drives listed. If you click on the icon here for your USB you might be able to safely eject by right clicking and choosing "eject" which does the same thing as "safely removing" via the icon in the system tray.
In some circumstances, as long as you can be sure that at the time there is no data being trasnferred onto or off of the USB then you can remove it without "safely removing" that is to say, you can pull it out, but this is not ideal and can corrupt data on the USB if done while there is data going between it and the pc. The wholw idea of "safely remove" is that it ends the flow of data so that you can then remove the USB.
