Making Raid storage the default storage

[dmainou]

Hi guys,

Total noob here.

Would you please be so kind to point me out how to start using my raid block as primary storage?

Just installed MCE on drive "a" and added a Raid5  block "b". 

Now when I navigate from the tv screen into media>manage drives I am unable to see the raid storage.

However, from the admin website I am able to see the the block when I go to Advanced>Configuration>raid.

Also do I need to create certain folder structure or can I use my own?
