Is there an "unallocated" space on the drive inside disk management? If so, you can right click & "extend"

o it just says unallocated 178gb

That would be right 478GB available on a "500GB" drive.. Does it give you the option to "extend"?

Does the unallocated space appear on the left or the right of your ~300GB partition?
