Using dd to create a recovery disk?

[Rainbow Asteroids]

I need to make a chrome os recovery disk, but I have linux, I found the .bin file I need, I'm just curious if I can use data duplicator to make a recovery disk?

Yes - In fact there is a little used ChromeOS Recovery Tool for Linux

Just run

wget https://dl.google.com/dl/edgedl/chromeos/recovery/linux_recovery.sh

chmod +x linux_recovery.sh

sudo ./linux_recovery.sh

You can of course look at the source code and see that it uses dd at its core - specifically 

dd bs=4194304 of=/dev/${user_choice} if="$image_file" conv=sync ||
  ufatal "Unable to write the image."
sync

Oh, I never knew that tool exists, all I saw was Linux not supported when I installed the chrome store one. Never really looked into it.

Rainbow,

You can use the Linux script mentioned above to grab a fresh image file if you like but if you already have the '.bin' file you need just open up the Chromebook Recovery Utility and select 'Use local image' from the drop-down menu.  It supports '.bin' files and '.zip' files too.

I use it like a gui frontend for 'dd' to burn ISO images and other things, just append a '.bin' suffix to an '.iso' file and you're good to go.
