Laptop cannot see my External Hard Drive, but other devices

Hi,
       I cannot see my external hard drive, a WD Elements Portable Hard Drive - 1 TB, on my Laptop. When I connect it to my main PC, or even my Windows Bootcamped Mac, it can view the device.



I've already Googled and tried the following solutions:



1) In Disk Management, uninstall driver. (I cannot do this as I cannot see the hard drive in there)

2) In Device Manager, view hidden devices and uninstall all greyed out devices. (This does not work when I plug the device back in.





Anyone have ideas on how to fix this?


Please help.

Thanks!



I didn't find the right solution from the Internet.
