Its saying Its there but not doing anything!


So I’ve had my MyBook Essential 2TB for three months now, and up until now  its been working great! However today its not working. My friend unplugged it from my computer while I was watching a movie on MyBook and when I went to go plug it back in, it didn’t come up. Its showing under my devices and printers but its not letting me open or do anything with it. I’m not really the best with computers, so any answers I need in basic form.  


ps. I have windows 7 on my computer

The drive may be corrupt from not disconnecting properly.

Try running chkdsk on it.
