Failed to start erase of disk due to error (-9999, 0).

[JLEW700]

Trying to create a bootable usb following these instructions

http://howto.cnet.com/8301-11310_39...-a-bootable-os-x-mavericks-usb-install-drive/

But when I copy and paste the command to terminal it gives me this error: "Failed to start erase of disk due to error (-9999, 0)."

Does anybody know how to fix this?

I ran into the same problem, and posted about it here with a set of simplified instructions and a link to the original source if you need more details.
