Hi Everyone, I'm trying to use my disk utility to move my OSX Snow Leopard onto it since I'm about to replace my hard drive - don't have original discs. Anyways, I've done everything I should to get this to go onto my USB drive but I still get the "resource busy" error. I've unmounted multiple times, restarted and I still get this error. I've attached images for you to see. I've partitioned right according to tutorials. Please if anyone has any help I'd really appreciate it.
