I bought a 1TB WD HDD a week ago. I copied a bunch of movies in but when I got home and tried to watch the movies in my laptop, the drive is not showing under my computer. I went into computer management and under Disk Management I saw my passport under Disk 1, Disk 0 is showing as my Drive C. I tried to change the drive letter coz I was thinking that was the problem, but it will not allow me to change the drive letter. Please help. Thank you.
