Easy solution:
Go into disk management and you will see the HDD (it will say unallocated space).
Next, simply right click and format the disk (NTFS is recommended).
It only shows up on the bottom, not at the top where it has the volume, layout, type, file system, status, etc..
When I right click the bottom it only says convert to dynamic disk, convert to GPT disk, and properties.
Do you know what to do here?
