I just attempted to create a USB key for Chrome OS. I followed the instructions found here. This is what I did:
1- Downloaded a .zip version of the build.
2- Extracted the .zip file which gave me a .img file.
3- Tried to burn the .img file to the USB key with the following command:
dd if=ChromeOS-Vanilla-3812.0.2013_03_08_1632-r10c5647c.img of=/dev/sdc1 bs=4M
4- That gave me a Permission denied error so I tried:
sudo dd if=ChromeOS-Vanilla-3812.0.2013_03_08_1632-r10c5647c.img of=/dev/sdc1 bs=4M
which seemed to work (at least it ended with a message that ~2.5Gb had been copied to the device)
But now if I insert the USB key the system does not recognize it anymore. I tried booting my laptop with that USB inserted but it did not pick it up either. Did I just destroy my 16Gb USB key?? Cheers.
Update: the Disk utility does recognize when the device is inserted. I tried to format the USB key with this app but got the error:
Error synchronizing after initial wipe: Timed out waiting for object (udisks-error-quark, 0)
Update 2: fdisk apparently also recognizes the device. The command sudo fdisk -l returns:
Dispositivo Inicio Comienzo Fin Bloques Id Sistema
/dev/sdc1 * 32 31270911 15635440 c W95 FAT32 (LBA)
(my system is in Spanish)
