I purchased a laptop a little over a year ago that came with a 1tb hard drive but in file explorer under this pc it says that I have two hard drives. I was not having any trouble with this until now because the one of the drives is almost full. The one I have been storing everything in is the os install drive (the C: drive) with 558gb of storage and another (D: drive) with 352gb of storage. Not only is this not a whole terabyte but I am also not looking forward too needing to deal with reorganizing things so that all of my steam files stay on the same drive. Any input would be greatly appreciated.
