Sql Server won't care about the drive size unless you tell it to (such as expanding a filesize manually), or it needs to autogrow an existing file. Then it just tries to grow unless your drive complains.
So, I'm not sure why you want SQL Server to detect the drive size?
Never stop learning, even if it hurts. Ego bruises are practically mandatory as you learn unless you've never risked enough to make a mistake.
