How to get rid of timer thing on icon and get back to normal

Hi there WD users. I bought a WD passport studio and have unwrapped it and tried it out with my macbook pro. Seemed like it was all going well and I managed to copy my files from my computer, understand the general scheme of things. But then I tried to download the turbo thingo and my computer shut down and  restarted as per instructions. But now my icon has the timer thing on it and I cannot get in. Pray tell, what have I done and how do I reverse it? Finding the virtual manual would be good too as that also seems to have disappeared off my screen. 

Best, Hamish
