###Mount disk on folder
  #To partition & format new drive:
  #Find disk (eg. /dev/sda)
sudo fdisk -l
  #Partition disk
sudo parted /dev/sda mkpart primary ext4 0% 100%
  #Format partition
sudo mkfs.ext4 /dev/sda1
  #Mount disk (test first, then edit fstab) (nofail will allow pi to boot even if disk is missing)
sudo mount /dev/sda1 /home/pi/nas0
sudo nano /etc/fstab
	/dev/sda1              /home/pi/nas0             ext4      defaults,nofail              0      2
  #Change ownership, permissions
sudo chown pi -R /home/pi/nas0
sudo chmod 777 -R /home/pi/nas0

###Setup Network
nano /etc/network/interfaces
source-directory /etc/network/interfaces.d

auto lo eth0
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet static
address 192.168.2.66
netmask 255.255.255.0
gateway 192.168.2.1

nano /etc/dhcpcd.conf
	as above, nameserver = 192.168.2.1 8.8.8.8 [something in hex]
	
  #Change Hostname
sudo nano /etc/hostname
  #Replace with occam
sudo nano /etc/hosts
	# add occam 127.0.0.1

###Install Samba
sudo smbpasswd -a pi	//enter password for remote entry
sudo chown -R <user_name> /etc/samba/smb.conf
nano /etc/samba/smb.conf
  #Add the following
[NAS0]
	comment = share-read-write
	path = /home/pi/nas0
	read only = No
	create mask = 0777
	force create mode = 0777
	directory mask = 0777
	directory mode = 0777
	force directory mode = 0777
	guest ok = Yes
	
Test param file: testparm

###Install MiniDLNA:
apt-get install minidlna
nano /etc/minidlna.conf
		DON'T SET AUDIO FOLDER TO 'A' - This will make it ignore playlists!
	Rebuild library: sudo service minidlna force-reload
	https://help.ubuntu.com/community/MiniDLNA
	
	
###Install Apache:
apt-get install apache2
Restarting: sudo service apache2 restart
Content:  /var/www/html
Set permissions: sudo chmod 777 /var/www/html
Settings:  /etc/apache2
