Raspberry Pi -- Installing Samba (Windows Share) File server

Having successfully run Debian Wheezy on my Raspberry Pi, I went forward with my initial idea of setting up a low cost power efficient file server for accessing my external hard disks from my Windows7 desktop, HP-Mini running Ubuntu and Mac Mini running OS X Lion (yeah I do like bragging about my machines :D ).

This turned out to be pretty straight forward.

As expected, the external Seagate USB disk immediately got recognized and appeared as /dev/sda

[  579.948350] usb 1-1.2: New USB device found, idVendor=0bc2, idProduct=3001
[  579.948384] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3

Next step is to create a mount point

pi@raspberrypi ~ $ sudo mkdir /media/terradisk

Add the correct entry to /etc/fstab (edit this with your preferred editor)

pi@raspberrypi ~ $ sudo vim /etc/fstab

So that it looks like the following,

And mount it

pi@raspberrypi ~ $ sudo mount -a

The new usb drive should now show up

Next install samba,

pi@raspberrypi ~ $ sudo apt-get install samba samba-common-bin

Once finished, open the samba configuration file

pi@raspberrypi ~ $ sudo vim /etc/samba/smb.conf

and edit as follows.
In the Authentication section, uncomment

   security = user

and add the following section in the end

[SamDataDump]
comment = Data Dump on Sam Raspberry Pi
path = /media/terradisk
writeable = yes
guest ok  = no

Remember to change

[SamDataDump]

with the share name you want and

path = /media/terradisk

with the path to wherever you mounted your external disk.
Add the smb password for the default pi user

pi@raspberrypi ~ $ sudo smbpasswd -a pi

Set permissions so that pi user can access the share,

pi@raspberrypi ~ $ sudo chown -R pi:pi /media/terradisk/

Restart samba

pi@raspberrypi ~ $ sudo /etc/init.d/samba restart

And done!
Try accessing the share,

 And it works!
