Hey master G hopefully I've managed to sort this now.
Bh was still playing up and green screening so I started from scratch and installed vix
Managed to mount it and then create swap file. Previously I was mounting the HDD as media HDD and not media USB as I didn't know the difference. So set it up as USB and it allowed me to create the swap file. I then changed the recording settings to the correct paths as well.
I set the swap file to 96m as well.
Thanks for your help
