Posting from Microwatt 64bit, thank you biff.
Couple of notes, if you're dual booting with Windows 7/8/10 - you can't access there drivers, it says you're not permitted to access the drive. I can see USB drives mounted though.
And 2nd: Again, if you're on Windows 7/8/10 and you use Rufus to create the bootable media, it doesn't boot and will load you straight in to Windows instead of booting from USB.
I use this:
https://sourceforge.net/projects/usbwriter/Ran as admin and created the bootable media that way in Windows 10.
Any idea on accessing the Windows drives, biff?
EDIT1: Ok, so install this:
sudo -i
root
sudo apt install gnome-disk-utility.
still in terminal as root:
gnome-disks
click the mount button and you can see your windows files.
EDIT2: After I restarted my PC, I can now access both of my hdd's. I disabled auto mount and the settings are:

exec --no-startup-id xrandr --output HDMI1 --auto --left-of DP1
edit for your monitor settings, you can check with:
xrandr.
EDIT4: as you can see from my screenshots, I am using dual monitors.
