I have two of the same hard drives. exactly the same. one of them all of my stuff is on, and the other i can not get to work at all. i can see them both in disk management but not in the computer folder. they are both Hitachi HDS723020BLA642 2TB HDD. I can not make any partitions or anything. the only option it gives is to convert to a dynamic disk, and it says there is not enough space. obviously something is wrong. Is it that they are the exact same, or something else?
if it is that they are the same, easy fix. if not, please help
