1.5TB WD external hard drive not recognized by computer

Hello,
i just got a new school laptop today (from school) (lenovo think pad yoga (running windows 8.1) and on bringing it home i plugged my hard drive in to the computer it worked a first but after plugging it in for the second time it no longer worked. the computer still made all the sound when you plug and unplug the hard drive and all the lights on the hard drive still worked but it did not show up in my computer or disk management. i then tested it on another 2 computers and it worked on both. the only difference between the other 2 computers and this one was the operating system (they both ran windows 7) and i am not sure if this would effect it or not

thanks for your help!
