Yes, it looks to be OK,
but as you Said.. Your Primary is Still on the Local C-Drive..
So any New Cards you BUY and Add, will First be stored on the C-Drive..
This is why, When I created my Triple Storage Drives..
I started by First Moving my Entire Collection to an External Drive.
Then I created the Junctions Back to the Local C-Drive, and some Junctions to a 3rd USB hard Drive.
Then Any NEW card will go the the External drive, and not my C-Drive.
(I'm no Longer doing this, as I have now a Big enough Single Drive. )
