I was playing around with a external hard drive on my computer recently and was loading Windows onto it to boot from the drive on my new computer. So I changed some things but I'm not sure exactly what but I know I did create a partition. So my dad needed to use it and when he took it to his computer the LED light at the top of the drive turned blue instead of white and wouldn't be recognized in the computer. I checked in the computer management and it is not even listed on it. I can feel all the insides moving. Everything works on my computer when I plug it in and it is recognized on mine but it is opposite for my dad's computer. I'm not sure what to do! Please help!!!!
