I just recently bought an XB1 and wanted to watch a movie the other night. So, not knowing that new xbox's don't play media off of external HDDs like the 360s did, I plugged in my hard drive and the Xbox reformatted the HDD. To my disappointment, I can't watch my movie collection through my new xbox. Anyway, when I plugged my HDD back into my computer, I found out that my computer does not even recognize the drive anymore. I understand that I have to reformat the drive for PC but I don't quite know how and I would really like to do it without losing all of my movies if they are even still there... Your help is greatly appreciated!
