How do I set up an SSD+HDD Win 8.1 UEFI install properly?

This is just for future reference so I can write stuff down. I already know HOW to install Windows 8.1 in UEFI Mode to an SSD, but there's something that I don't understand and I need specifics on it. Building a computer in the future, yay, and gonna run it with an 120GB SSD as a boot drive and a HDD to hold my programs and to store my files.

I plan to install via DVD, and the common guide suggests not connecting the secondary drives so the OS doesn't confuse the drives or whatever.

But I'm confused as to whether or not the OS will detect the HDD when I plug it in after the OS is installed? Is there anything special I need to do so as to start using it to store files? Will Windows automatically format it and use it properly or what?

Install the SSD > install windows > shut down PC > install HDD

Windows will find and ask to initialize and format if needed

So it's literally as easy as just plugging in the HDD? O_O

When i installed Windows 8.1 Pro had all drives installed OS on one SSD and had a second SSD plus a HDD in system at the time of install done UEFI.
GPT style for the 2 SSD's and i setup the HDD MBR from disk management. HDD for backup (Data) second SSD for games.
Possible either way of course.
