Usb will not connect and driver will not install

I have a My Book that is two years old. I recently instyalled Windows 7 on my laptop. I tried connecting the My Book but recieved messages that the computer does not recognize the device. After the third attempt, I do not get the fail message but it is still not connected.  I tried to install  the extfat32 but the  attempt failed. 

You’ve posted your query to the wrong forum.

Can you post the model number of your drive?
