The PC booted as normal when I turned it on, and the greater space showed in the 'C' drive. I then turned my PC off, and simply swapped out the smaller one, for the bigger one inside my case. I used the Samsung Data Migration software to clone my smaller Samsung SSD onto my new larger SSD. Previously I had a 250GB 840 EVO, which worked perfectly via the Magician software.
JUst upgraded to a 1TB Samsung SSD EVO 860.
