I have a Asus ROG maximus xi hero and I installed a 1tb Corsair M.2 SSD. I only have two storage devices (hard drive-500gb/m.2 ssd-1tb). When I search for storage devices, two show up one 500gb and another close to 1000gb. The 1000gb one says that all of its storage is already being used and there is a partition within the ssd stopping the storage from being 1tb.
