Important information This tutorial is out-dated and has been updated here: In this tutorial, I’m going to talk you through running Raspbian from a USB connected drive instead of from an SD card. If you run Raspbian from a USB Flash drive, you will enjoy performance boosts, speed and reliability improvements just to name a few benefits. SD Cards have a limited read/write cycle, and when hosting a site with a MySQL database from a SD card, it won’t take long before you start getting corruptions and failures.

I’ve tested several USB Flash drives, and found Sandisk and Corsair to be the best for speed and reliability. This site is run off a 16GB Corsair Voyager 3 USB Flash drive. Assumptions before we begin I’m going to assume that you know your way around Terminal, and are using a Mac to perform these steps. The Raspberry Pi is a great, versatile piece of kit, capable of projects as diverse as running a media center to use as a broadcast radio. But it has one glaring flaw: the inability to boot from USB. Well, until now, that is. This command adds the program_usb_boot_mode=1 instruction to the end of. The image files will start writing on the disc and soon you will have a bootable disc/disk. Testing The Disc/Disk. Parallels desktop for mac student license renewal. Before testing the disc, make sure that the Optical Drive is on the top of the list in the boot order. You will still need an SD card to store the boot instructions to tell the Raspberry Pi to launch the OS from the USB; the Raspberry Pi’s can’t (yet) boot directly from a USB storage device. Step 1 – Download Raspbian from Raspberry Pi You will need the standard Raspbian OS image, you can download this from the official. Once you’ve downloaded it, unzip it. It’s around 400mb in size, so should only take a couple of minutes over a broadband connection. Step 2 – Install the Raspbian OS to your USB Flash drive Plug in your USB stick and launch Terminal. The first thing we’re going to do is get the device identifier for your USB Flash drive. To do this run the following command: diskutil list The list of attached disks will show up with their identifiers. Important – make a note of the correct identifier, you can do some serious damage by choosing the wrong one! In the screen shot above, I can see that /dev/disk2 is the correct identifier for my Sandisk USB Flash Drive. Yours may be different so change to suit your configuration. Next we’re going to unmount the USB Flash Drive. To do this enter the following command: diskutil unmountDisk /dev/disk2 Yet again, be really careful to change disk2 to whatever your computer identifies the USB Flash Drive as. You will get a message saying “Unmount of all volumes on disk2 was successful”. Now we can begin the copy. For ease, I’ve changed the directory in Terminal to where the Raspbian image is located, which in this case is my downloads folder. If you’ve downloaded and unzipped the disk image to your downloads folder, running this command should take you there: cd ~/Downloads/ Now run this command to begin the copy: sudo dd bs=1m if=2013-02-09-wheezy-raspbian.img of=/dev/disk2 As with before, make sure you change disk2 to whatever your computer identifies as being the USB Flash Drive, and change 2013-02-09-wheezy-raspbian.img to whatever your image file is called. The blocks will now begin moving to your USB Flash Drive from the Raspbian OS image. This takes anything from 5 to 20 mins depending on the speed of your USB Flash Drive. Go stick the kettle on and have a brew! Eventually, you will see something similar to the above, and it probably took a while too.
