[Questions: DrivePool and Adding HDD's]

I think you posted this on the Home Server Show forums too. And I think I answered there first.

 

Yes I did and you did too, helped me immensely! Thanks 

[Questions: DrivePool and Adding HDD's]

I've been running my first server (a Gen8 w/ WHS2011) for about a year and I'm about to add a 4TB Red to the rack (along with the existing 60GB SSD and 2TB Red) (see image attached).

 

 

So I decided to get DrivePool so I can consolidate all my files into the one place when I add the new drive.

 

My questions are as follows:

1. What is that (D:) drive? It's always been there...
2. What's the best way to "move" everything from (F:) into the DrivePool (E:) and switch the mapped letters so that I don't have to change any file paths?
3. Can I "move" everything from the SSD (C:) into the DrivePool and get the software to recognise that program files need to remain on the SSD and not get balanced to anywhere else?
4. How do I add the new drive when I get it? Is it just plug-and-play?

Can't wait for feedback. Thanks, Watson.
