Scenario: Friend of mine has a 500Gb HDD, which is full of games and he's running out of space. So he wants to buy an extra 1/2TB drive, and the question is can he combine them logically into one big C:// drive? Now, I believe there is an issue with having over 2.2TB as a booting drive and using MBR instead of GPT? But say with a 1TB drive then, is there any way he can combine his existing 500Gb drive with all his games and the OS with the new 1Tb drive to make 1.5TB C:// drive? With, or without, having to reinstall everything?
