Drives formatted as FAT or NTFS can be mounted in WSL.
Assuming the drive appears in Windows as E:\ then

The commands below are typed into the WSL cli.

Create a mount location in WSL

# mkdir /mnt/e

Mount the drive in WSL:

mount -t drvfs e: /mnt/e

Firstly - set the default user to be "root" like this:
At at CMD prompt with Administrator rights:
C:\WINDOWS\system32>ubuntu config --default-user root

Then open WSL and run:
# passwd defaultuser
To set the password for your preferred user (in example: "defaultuser")

Then, 
At at CMD prompt with Administrator rights:
C:\WINDOWS\system32>ubuntu config --default-user defaultuser
