I have several 2010 macbook airs, thus, i have several of the USB restore drives and I would like to restore one of them with a general version of OSX to use on other machines, I have read the stick is protected but I would assume there is some workaround to delete its contents and restore with a full version of snow leopard for all macs. People have presented the solutions of buying other flash drives, that is not what i want to do I want to use this specific drive. I would love to hear of any success with doing something like this or any tips.
