Writing BoardRestore to a 4gb+ USB 3.0 drive on Windows

Follow the below procedure word-for-word and do not skip any steps in order to successfully write BoardRestore to your USB 3.0 drive.
  1. Download the BoardRestore archive (ending with .xz)
  2. Download 7-Zip (available at https://www.7-zip.org/) and extract the archive using Right Click -> 7-Zip -> Extract Here, it will extract into approximately a 2GB .img file.
    NOTE: Do not use the native Windows unzip utility. If you use it, the archive will not extract properly, and will be corrupted.
  3. Download Rufus (available at https://rufus.ie/) and launch it.
    NOTE: Do not mount the BoardRestore .img file using Windows.
  4. Plug in your destination USB 3.0 drive. After it is plugged in, launch Rufus.
    NOTE: Do not use a USB 2.0 drive, they are too slow.
  5. Select the BoardRestore .img file as your SOURCE. Select your USB 3.0 drive as your DESTINATION. Rufus will clone BoardRestore onto the USB 3.0 Drive.
  6. The BoardRestore USB drive is now ready for use.

Writing BoardRestore to a 4gb+ USB 3.0 drive on Linux (debian/ubuntu flavors)

  1. Download the BoardRestore archive (ending with .xz) and uncompress it with unxz /path/to/boardrestore-*.xz, it will extract into approximately a 2GB .img file.
  2. Confirm the location of your source BoardRestore .img file: ls /path/to/boardrestore-*.img
  3. Plug in your destination USB 3.0 drive.
    NOTE: Do not use a USB 2.0 drive, they are too slow.
  4. Confirm that your computer sees your destination drive. You should see the destination drive appear as /dev/sdX where X is your enumerated drive (i.e. /dev/sdb):
     dmesg | grep sd
     fdisk -l | grep sd
    
  5. Confirm that your destination drive is correct with smartctl: apt-get -fy install smartmontools smartctl -i /dev/sdX (replace X with your enumeration)
  6. Clone your source to your destination:
    IMPORTANT: if you make a mistake and accidentally clone to an incorrect drive, you will cause CATASTROPHIC DATA LOSS. apt-get -fy install gddrescue ddrescue --force -r2 /path/to/boardrestore.img /dev/sdX (replace /path/to/boardrestore.img with the full path to the BoardRestore version you downloaded, and replace X with your enumeration)
  7. Watch the progress. ddrescue should finish with no errors. After it is done, it is safe to shutdown and power off your computer.
  8. The BoardRestore USB drive is now ready for use.

    NOTE: Full command looks like sudo dd if=/Users/YOURUSERNAME/Desktop/boardrestore-*.img of=/dev/rIDENTIFIER bs=1m (note the r before IDENTIFIER)
  10. Press the Enter key and wait for the disk imaging process to complete.
  11. When the process completes, you might get message alert saying that the drive is not readable. Eject the drive at this point.
