Now we’re ready to do the difficult parts.
Write the Raspbian Linux OS image to the micro SD card. I use a Mac so I use the following instructions: https://www.raspberrypi.org/…/inst…/installing-images/mac.md
Note that when you are in the Mac’s System Report window, expand Hardware -> USB -> USB2.0 Hub -> USB 2.0 Hub then click on USB Storage. Or whatever you do, find that USB Storage node. In the details panel below on the right you’ll find “BSD Name”, in my case it is disk5, that’s the micro SD card we’re writing the image to (the Pi instructions missed this very tiny important detail).
If you use Windows then use the following instructions:
For Macs, when you use the sudo dd command to write the image to the micro SD card, a progress update won’t be displayed. Instead press Control-T to see a status update when you want.
The process takes about 4.5 minutes on my Mac. It’ll be roughly the same on other computers as the time is dependent on the USB 2.0 port and microSD speed. I have a Class 10 micro SD card, which is pretty fast at the time this is posted.
Once you’re done with writing the Raspbian Linux OS image, boot up the Pi.
It is already preconfigured to provide X Window for a GUI display, and the network is preconfigured to use DHCP.
It’s now a ready to use Linux desktop, though I like the term tinypute myself
Next we’ll install and build the RAID 5 array itself …
