I recently bought a 2TB My Book Essential USB 3.0. About 2 weeks ago i unplugged the My Book to move it and when i plugged it back in it showed up as a Local Drive G: and then it says if i want to format it. I do not want to format it until i try other solutions. I am currently using it on Windows 7. Also It was first used on my desktop with vista but i no longer use the desktop so i just use it with my laptop now.
Also under disk management it says RAW instead of NTFS.
