There are several ways to get an USB-disc drive (stick) with Knoppix Adriane software and educational content for blind users:
- you can ask Labdoo to send out a ready installed USB-disc drive (stick) by sending a m to Labdoo-DACHqLabdoo.org (only for Austria, Germany and Switzerland). Tell us how many USB-Discs you need and your postal address. Please understand that we have to cover the costs by donations.
- Or you produce an USB-disc drive yourself (only recommended for advanced users!) It will NOT WORK to copy an USB-disc to another USB-disc using a file manager. Some important data like boot information (MBR) will not be copied and will not be able to boot this stick. Labdoo recommends minimum 16 GB USB 2.0 disc drives to store Knoppix Adriane, local Wikipedia for Schools and ca. 6GB free space for user data.
You can get another USB disc drive
- by copying a pre-installed USB-disc drive to another drive using Linux and the dd command (for details see below) or
- download an image and restore it using dd command..
Method 1: Copy one pre-installed USB-disc drive to another (only for experienced users)
You already have got a pre-installed USB-disc drive Knoppix Adriane by Labdoo? Then buy an USB-disc drive (min. 16 GB). As only very few of the computers abroad have USB 3.0 slots we recommend to buy fast USB 2.0 disc drives. On older hardware USB 3.0 discs might not be recognized.
You can do de copy using a Labdoo- or Linux laptop:
Start the Labdoo-/Linux computer and log-in as user labdoo. Important: First plug-in the pre-installed origin USB-disc (which you want to copy, will usually get the name /sdb), next plug-in the USB drive you want to copy to (will get drive /sdc etc.) You are also able to copy several sticks at the same time (will become drive /sdd, /sde etc).
Open a terminal and run
lsblk -f (Enter). This will give you a list of all available drives. The drive /sda (mit den Partionen /sda1, /sda2 usw.) is the internal drive of the laptop. Never touch that! Leave it as it is!
Next step is to run in a terminal:
sudo dd if=/dev/sdb of=/dev/sdc status=progress Enter; this will copy all data from the origin USB drive (/sdb) to the target USB drive (/sdc etc.). This will take a while...
Attention: the command dd is helpful, but also dangerous! Check always, if origin and target drive are correct. Otherweise you might delete your own computer's data by mistake. We recommend not to use your own computer, but a Labdoo computer since dd is available on each Linux computer.
Method 2: Restore the image Knoppix_Adriane_dd_xx.gz using dd to an USB disc drive (only recommended for experienced users)
Download from the Labdoo FTP-Server the images (we created them using dd): http://ftp.labdoo.org/download/install-disk/ (the images are named Knoppix_Adriane_dd_xx.gz, xx being space-holder for the language, EN = Englisch, FR = Französisch, DE = Deutsch, ES = Spanisch)
Store the downloaded, zipped file in your home directory (/home/labdoo). You don't need to unzip it first. Next step is to connect the target USB disc drive to the computer, open a terminal and execute :
lsblk -f(Enter), to check if all drives are connected (in most cases the internal disc of the computer is /sda (do not delete that one!) and the connected USB disc drive becomes /sdb, /sdc etc.
sudo gunzip -c Knoppix_Adriane_dd_xx.gz | sudo dd of=/dev/sdb status=progress(Enter, xx = space-holder for the language, replace accordingly). This will unzip and copy all data of the image to the USB drive. Change drive name accordingly if needed, e.g. /sdb in /sdc etc. if copying several USB drives in parallel
After copying all data to a new USB drive you can unmount (remove secure) and shut down the computer. To use this new USB drive with a computer we recommend to change the boot sequence in BIOS settings. The USB-(stick) should be placed (get a higher boot priority) before the internal disc drive. Otherwise you can select manually the boot media each time you boot (often press F12). But for blind users this might be difficult.
- Internal: Create an image using Shell and dd (only recommended for experienced users!)
- Open a terminal and execute
sudo dd if=/dev/sdb status=progress | gzip --best >Knoppix_Adriane_dd_xx.gz(Enter, replace xx by the language code you need). This will copy a zipped image file Knoppix_Adriane_dd_xx.gz an (ca. 12 GB) to your home directory /home/labdoo.
To get an image from an ready installed USB disc drive with Knoppix Adriane use dd as well. In most cases the USB disc, to copy from, has the address / drive name /sdb (might change, so please check).
Create image by terminal (shell)
